Hi,

I’m using Apache 2.2 on Fedora Core 6 Linux. I’m using ruby 1.8.6 and  
mod\_ruby 1.2.5. I get this error when starting Apache:

[Wed Jan 16 09:40:26 2008] [error] mod\_ruby: failed to require apache/  
ruby-run  
[Wed Jan 16 09:40:26 2008] [error] mod\_ruby: error in ruby  
[Wed Jan 16 09:40:26 2008] [error] mod\_ruby: ruby:0:in `require’: no  
such file to load – apache/ruby-run (LoadError)

Does anyone know what could be causing this? I’m including my  
httpd.conf file if that is useful:

==================Begin httpd.conf file========================

# 

# This is the main Apache HTTP server configuration file. It contains

the

# configuration directives that give the server its instructions.

# See URL:http://httpd.apache.org/docs/2.2 for detailed information.

# In particular, see

# URL:http://httpd.apache.org/docs/2.2/mod/directives.html

# for a discussion of each configuration directive.

# 

# Do NOT simply read the instructions in here without understanding

# what they do. They’re here only as hints or reminders. If you are

unsure

# consult the online docs. You have been warned.

# 

# Configuration and logfile names: If the filenames you specify for

many

# of the server’s control files begin with “/” (or “drive:/” for

Win32), the

# server will use that explicit path. If the filenames do _not_ begin

# with “/”, the value of ServerRoot is prepended – so “logs/foo.log”

# with ServerRoot set to “/usr/local/apache2” will be interpreted by

the

# server as “/usr/local/apache2/logs/foo.log”.

# 

# ServerRoot: The top of the directory tree under which the server’s

# configuration, error, and log files are kept.

# 

# Do not add a slash at the end of the directory path. If you point

# ServerRoot at a non-local disk, be sure to point the LockFile

directive

# at a local disk. If you wish to share the same ServerRoot for

multiple

# httpd daemons, you will need to change at least LockFile and

PidFile.

# 

ServerRoot “/usr/local/apache2”

# 

# Listen: Allows you to bind Apache to specific IP addresses and/or

# ports, instead of the default. See also the

# directive.

# 

# Change this to Listen on specific IP addresses as shown below to

# prevent Apache from glomming onto all bound IP addresses.

# 

#Listen 12.34.56.78:80  
Listen 80  
Listen 443  
  
ServerName [http://remandev.no-ip.org](http://remandev.no-ip.org)

SSLCertificateKeyFile /usr/local/apache2/ssl/remandev.no-ip.org.key

# 

# Dynamic Shared Object (DSO) Support

# 

# To be able to use the functionality of a module which was built as a

DSO you

# have to place corresponding `LoadModule’ lines at this location so

the

# directives contained in it are actually available _before_ they are

used.

# Statically compiled modules (those listed by `httpd -l’) do not need

# to be loaded here.

# 

# Example:

# LoadModule foo\_module modules/mod\_foo.so

LoadModule php4\_module modules/libphp4.so

# 

```
  AddType application/x-httpd-php .php .phtml
  AddType application/x-httpd-php-source .phps

```

# Allow for ssl

#LoadModule ssl\_module modules/libmodssl.so

\<IfModule !mpm\_netware\_module\>

# 

# If you wish httpd to run as a different user or group, you must run

# httpd as root initially and it will switch.

# 

# User/Group: The name (or #number) of the user/group to run httpd as.

# It is usually good practice to create a dedicated user and group for

# running httpd, as with most system services.

# 

User daemon  
Group daemon

# ‘Main’ server configuration

# 

# The directives in this section set up the values used by the ‘main’

# server, which responds to any requests that aren’t handled by a

# definition. These values also provide defaults for

# any containers you may define later in the file.

# 

# All of these directives may appear inside containers,

# in which case these default settings will be overridden for the

# virtual host being defined.

# 

# 

# ServerAdmin: Your address, where problems with the server should be

# e-mailed. This address appears on some server-generated pages, such

# as error documents. e.g. removed\_email\_address@domain.invalid

# 

ServerAdmin removed\_email\_address@domain.invalid

# 

# ServerName gives the name and port that the server uses to identify

itself.

# This can often be determined automatically, but we recommend you

specify

# it explicitly to prevent problems during startup.

# 

# If your host doesn’t have a registered DNS name, enter its IP

address here.

# 

#ServerName [www.example.com:80](http://www.example.com:80)

# 

# DocumentRoot: The directory out of which you will serve your

# documents. By default, all requests are taken from this directory,

but

# symbolic links and aliases may be used to point to other locations.

# 

DocumentRoot “/usr/local/apache2/htdocs”

# 

# Each directory to which Apache has access can be configured with

respect

# to which services and features are allowed and/or disabled in that

# directory (and its subdirectories).

# 

# First, we configure the “default” to be a very restrictive set of

# features.

# 
 Options FollowSymLinks AllowOverride None Order deny,allow Deny from all
# 

# Note that from this point forward you must specifically allow

# particular features to be enabled - so if something’s not working as

# you might expect, make sure that you have specifically enabled it

# below.

# This should be changed to whatever you set DocumentRoot to.

# 

\<Directory “/usr/local/apache2/htdocs”\>  
#  
# Possible values for the Options directive are “None”, “All”,  
# or any combination of:  
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI

#  
# Note that “MultiViews” must be named _explicitly_ — “Options  
All”  
# doesn’t give it to you.  
#  
# The Options directive is both complicated and important. Please  
see  
# [core - Apache HTTP Server Version 2.2](http://httpd.apache.org/docs/2.2/mod/core.html#options)

# 

# ErrorLog: The location of the error log file.

# If you do not specify an ErrorLog directive within a

# container, error messages relating to that virtual host will be

# logged here. If you _do_ define an error logfile for a
# container, that host's errors will be logged there and not here. # ErrorLog logs/error\_log
# 

# LogLevel: Control the number of messages logged to the error\_log.

# Possible values include: debug, info, notice, warn, error, crit,

# alert, emerg.

```
#
# Alias: Maps web paths into filesystem paths and is used to
# access content that does not live under the DocumentRoot.
# Example:
# Alias /webpath /full/filesystem/path
#
# If you include a trailing / on /webpath then the server will
# require it to be present in the URL. You will also likely
# need to provide a <Directory> section to allow access to
# the filesystem path.

#
# ScriptAlias: This controls which directories contain server

```

scripts.  
# ScriptAliases are essentially the same as Aliases, except that  
# documents in the target directory are treated as applications  
and  
# run by the server when requested rather than as documents sent  
to the  
# client. The same rules about trailing “/” apply to ScriptAlias  
# directives as to Alias.  
#  
ScriptAlias /cgi-bin/ “/usr/local/apache2/cgi-bin/”

# DefaultType: the default MIME type the server will use for a

document

# if it cannot otherwise determine one, such as from filename

extensions.

# If your server contains mostly text or HTML documents, “text/plain”

is

# a good value. If most of your content is binary, such as

applications

# or images, you may want to use “application/octet-stream” instead to

# keep browsers from trying to display binary files as though they are

# text.

# AddType allows you to add to or override the MIME configuration

#AddType application/x-gzip .tgz

# AddEncoding allows you to have certain browsers uncompress
# information on the fly. Note: Not all browsers support this.
#
#AddEncoding x-compress .Z
#AddEncoding x-gzip .gz .tgz
#
# If the AddEncoding directives above are commented-out, then you

#
# AddHandler allows you to map certain file extensions to

“handlers”:  
# actions unrelated to filetype. These can be either built into  
the server  
# or added with the Action directive (see below)

# To use CGI scripts outside of ScriptAliased directories:  
# (You will also need to add “ExecCGI” to the “Options”  
directive.)  
#  
#AddHandler cgi-script .cgi

# For type maps (negotiated resources):
#AddHandler type-map var

#
# Filters allow you to process content before it is sent to the

# (You will also need to add “Includes” to the “Options”  
directive.)

#AddType text/html .shtml

# 

# The mod\_mime\_magic module allows the server to use various hints

from the
