I have the exact problem cugf described right down to using the same gem 
(selenium). I tried your first suggestion but that returned with a 
compile time error. I've wasted a day digging through google links 
without any luck but maybe I was searching for the wrong things. Here is 
what I have:

C:\Documents and Settings\user>gem contents selenium

c:/ruby/lib/ruby/gems/1.8/gems/Selenium-1.0.1/bin/selenium
c:/ruby/lib/ruby/gems/1.8/gems/Selenium-1.0.1/lib/selenium

c:/ruby/lib/ruby/gems/1.8/gems/Selenium-1.0.1/README

And the (very unhelpful) example selenium provides has the following 
requires:

require 'spec'
$:.unshift File.join(File.dirname(__FILE__), '..')
require 'lib/selenium'

I have no idea how to figure out what to require so I have to assume the 
example is exhaustive and correct. However, just using the lines above 
errors out on the first require with the reason: no such file to load. 
If it is a problem of not having rubygems loaded, would someone mind 
very much elaborating a bit on the 'export RUBYOPT=rubygems' stuff? 
Also, is there a way to discern what values should be specified in the 
require lines for a given installed gem? Is there a way to just require 
individual .rb files? In advance, thank you to anyone with information. 
Normally I wouldn't dare asking such simple questions but I cannot 
figure this out.
