# Unfortunately rubygems cannot be disabled because (at least)
# ActiveSupport leverages a gem load error to correctly create
# load paths:
#
#   [active_support/vendor.rb]
#   Prefer gems to the bundled libs.
#   require 'rubygems'
# 
#   begin
#     gem 'builder', '~> 2.1.2'
#   rescue Gem::LoadError
#     $:.unshift "#{File.dirname(__FILE__)}/vendor/builder-2.1.2"
#   end
#   require 'builder'
#   ...
#
# System gems CAN be disabled, however, so we know no gems will
# be loaded beyond those bundled.
