Glad to hear that someone else has proxy support working!

More to the point ... as well as paying attention to HTTP_PROXY, 
open-uri also honours the NO_PROXY environment variable. So even if you 
have HTTP_PROXY set, you can cause rubygems to not use it by setting 
NO_PROXY to gems.rubyforge.org.
