After about an hour on the rails IRC and talking with a friend over instant messaging about possible issues it ended up boiling down to openssl and openssl-dev not being installed. Install those but you’re not done yet.

cd to your ruby directory then go into the ext directory, once in there cd openssl; ruby extconf.rb; make; make install, cd ../; cd zlib; ruby extconf.rb; make; make install

And the shebang line: gem install rails –verbose and you should be all good to go now

Hope this helps someone else as google was pretty empty with any “resolved” solutions.

Was reading through my mailing lists and found this one in the Drizzle mailing list when talking about code styling for c++, pretty interesting read “Join Strike Air Fighter Vehicle C++ Coding Standards”

Another random musing when I was working on a rails project:
Even if your using the default environment for a cron job, you need to put RAILS_ENV=env /path/to/ruby etc…. in the command line for it to work (at least on CentOS)
