I believe you are looking for the $: variable (or the alias $LOAD_PATH):

irb(main):001:0> $:
=> ["/usr/local/lib/ruby/site_ruby/1.8", "/usr/local/lib/ruby/ 
site_ruby/1.8/powerpc-darwin7.7.0", "/usr/local/lib/ruby/site_ruby",  
"/usr/local/lib/ruby/1.8", "/usr/local/lib/ruby/1.8/powerpc- 
darwin7.7.0", "."]
irb(main):002:0> $LOAD_PATH
=> ["/usr/local/lib/ruby/site_ruby/1.8", "/usr/local/lib/ruby/ 
site_ruby/1.8/powerpc-darwin7.7.0", "/usr/local/lib/ruby/site_ruby",  
"/usr/local/lib/ruby/1.8", "/usr/local/lib/ruby/1.8/powerpc- 
darwin7.7.0", "."]

They're basically Arrays so you can push/unshift new entries.  The  
Ruby command-line option -I will also add directories.

Hope that helps.
