I’ve installed ruby and rubygems on leopard. when i install a gem  
successfully and run require “gemname” in irb it fails:

irb(main):001:0\> require “P4”  
LoadError: no such file to load – P4  
from (irb):1:in `require’  
from (irb):1  
irb(main):002:0\>

Yet here it is installed:

> gem which P4  
> (checking gem p4ruby-1.0.7 for P4)  
> /usr/local/lib/ruby/gems/1.8/gems/p4ruby-1.0.7/lib/P4.rb

Should I set an env var? If so, which and where?
