Your Windows installation probably automagically includes the gem path
in Ruby's search path (perhaps the installation you have includes some
gems, and so puts that in for you).

Try this:
irb(main):001:0> $:
=> ["/usr/local/lib/site_ruby/1.8",
"/usr/local/lib/site_ruby/1.8/x86_64-linux", "/usr/local/lib/site_ruby",
"/usr/lib/ruby/1.8", "/usr/lib/ruby/1.8/x86_64-linux", "."]
irb(main):002:0> 

You can see what paths are included in the search. You should always
require 'rubygems' before requiring anything you expect may be in a gem,
though, for maximum cross-compatibility.
