On Mac OSX 10.5 is ruby,irb,gem preinstalled in /usr/bin/ . I am not  
sure
on OSX < 10.5.
Maybe you can try if that works: /usr/bin/ruby -e 'require "rubygems"'

Maybe you have installed more than one ruby and irb on your computer.
If you run a zsh then you can ask with `where ruby`, where in the system
ruby is found.

If you installed ruby and irb from macports, then it will not find
rubygems, because you need the package rb-rubygems installed, too.
