Hi,

have you require'd rubygems? either require 'rubygems' or call ruby
with --rubygems or add rubygems to your $RUBYOPT variable.

I don't know how you can tell gems where to look for the files, but
from your printout it seems that gems are not loaded (you'd see
something like rubygems/custom_require in the output)
