I think you need to change the path where rubygems searches for 
libraries. You obviously have the "gem" executable, but gem is running 
"require 'rubygems'", which is failing. You should find rubygems.rb and 
note its folder. Say it's in /cygdrive/c/ruby/lib/, for example. You can 
start ruby with that information: ruby -I /cygdrive/c/ruby/lib/. It is 
up to you whether to type that manually each time you need to (i.e., 
ruby -I /cygdrive/c/ruby/lib/ /cygdrive/c/ruby/bin/gem install -r 
something), or write a wrapper script that calls the ruby executable 
with that argument. The second solution will work for any invocation of 
ruby, while you can obviously only utilize the first solution if ruby 
starts because you typed "ruby" on the command line (might as well use 
an alias, if that's the case).

But it seems like this shouldn't be a problem... are there any better 
ways to install ruby on cygwin? (I haven't used cygwin in years...)
