If your Ruby paths are set correctly, it's probably because you haven't 
loaded up RubyGems.  I don't blame you either.  I ran into the same 
thing when I started and it took me a while to figure it out.  There's 
three ways you can do this.

1. Require 'rubygems' in your source file
2. Run the script with the -rubygems switch
3. Set the RUBYOPT environment variable to 'rubygems'
