I am attempting to install 1.9.1 from source on CentOS 5.4 and am  
running into an issue.

after unpacking the archive and cd-ing into the ruby-1.9.1-p376 I run:  
./configure --with-openssl-dir=/usr/lib/openssl

but the last line of the output shows:  
config.status: creating Makefile  
configure: WARNING: unrecognized options: --with-openssl-dir

What do I need to do to get the creation of the makefile to not throw  
that warning?

Hi Cameron,

I am new to Ruby and I came across this same problem when I was  
installing  
ruby for the first time on my Ubuntu box. But after spending some time  
on  
it, I found the following steps works without much of a problem for  
installing ruby with openssl.

Ignore the --with-openssl-dir: I think the problem is to say with using  
[dash][dash]with-openssl-dir instead of [dash][dash]  
[dash][dash]with-openssl-dir. Google for the same and you will find the  
reason

Instead, try this approach:

1. Install ruby with ./configure --prefix = /installation\_path
2. Download openssl source and run ./config --perfix= /installation\_path  
Note: OpenSSL 1.0.X version doesn’t seems to be working with ruby.  
OpenSSL-0.9.8n worked for me. Also use the same $installation\_path for  
both  
‘prefix’ declarations. e.g., --prefix=/usr/local
3. Complete OpenSSL installation.
4. Go back to the ruby-1.8.6-pxxx/ext/openssl folder and run - ruby  
extconf.rb, make, make install respectively.

Now I am sure, all the required packages for openssl can be identified  
by  
ruby whenever required.

Hope this helps. I have also blogged about the same in the following  
location. Feel free to check this out too.

There’s no need to install openssl from source. Just install the  
openssl-devel package before building ruby (yum install openssl-devel)
