Hi all, I have some problems using erb(o erubis) + cgi  
I am able to use single rb files or rhtml, but when I try to use a  
structure  
like that:

file.rb+file.eruby

I have an internal server error (500)  
I know, these problems are really by newbie.

I show you my files.

* * *

## file.rb

#!/usr/bin/ruby  
require ‘rubygems’  
require ‘erubis’  
input = File.read(‘file.eruby’)  
eruby = Erubis::Eruby.new(input, :trim=\>false)

list = [‘aaa’, ‘bbb’, ‘ccc’]  
puts eruby.result(binding()) ## using eruby.evaluate(…)

* * *

## file.eruby

 \<% for item in list %\> - \<%= item %\> 
 \<% end %\>

opening file.rb in my browser (in the shell it works fine, showing me  
the  
html code) , apache server responds to:

[error] mod\_ruby: error in ruby  
[error] mod\_ruby:  
/usr/lib/ruby/gems/1.8/gems/erubis-2.4.1/lib/erubis/evaluator.rb:62:in  
`eval': Insecure operation - eval (SecurityError) [error] mod_ruby: from /usr/lib/ruby/gems/1.8/gems/erubis-2.4.1/lib/erubis/evaluator.rb:62:in`result’

`load' [error] mod_ruby: from /usr/lib/ruby/1.8/apache/ruby-run.rb:53:in`handler’

* * *

## My httpd.conf is like:

ScriptAlias /cgi-bin/ /usr/local/apache2/cgi-bin/

 UserDir public\_html

RubyHandler Apache::RubyRun.instance

# 

# # handle \*.rhtml as eruby files.

\<Files \*.rhtml\>  
SetHandler ruby-object  
RubyHandler Apache::ERubyRun.instance

Please help me in some way!

Thanks
