Despite some of the kind suggestions from others, the particular file
rubygems.rb should be in

.../lib/ruby/site_ruby/1.8/

if Ruby and rubygems are both installed.  Note that this is not the
gem binary, but rather the file which allows your program to load
gems.

The ... stands in for an installation path which varies from system to
system. But should be something like /usr or /usr/local on a Debian
based system.  Actually self installed stuff should be in /user/local
IIRC so as not to collide with packaged stuff.
