I hacked up a quick script (after digging through rubygem's sources):
PS C:\Scripts> ruby .\gemconfig.rb
sitedir: C:/Ruby/lib/ruby/site_ruby
bindir: C:/Ruby/bin
sitelibdir: C:/Ruby/lib/ruby/site_ruby/1.8
datadir: C:/Ruby/share
vendordir:
EXEEXT: .exe
libdir: C:/Ruby/lib
vendorlibdir:
ruby_install_name: ruby
RUBY_SO_NAME: msvcrt-ruby18
ruby_version: 1.8
arch: i386-mingw32
PS C:\Scripts> cat .\gemconfig.rb
require "rubygems"
Gem::ConfigMap.each do |config,value|
         puts "#{config}: #{value}"
end
PS C:\Scripts>

The path seems to be built on runtime (I don't have a .gemrc defined in 
my home dir).

So, this raises the question, if your production environment is isolated 
from the development and testing environments, and if so, how?
(Mind, this is a question out of curiosity, to get to the root of the 
problem :)
