You should look into GEM_PATH and GEM_HOME environment variables.

Merb is doing something similar, making their bundled gems first in
the search of GEM_PATH.

You can do something like this:

require 'rubygems'
Gem.clear_paths
ENV['GEM_HOME'] = File.join(Dir.pwd, 'gems')
ENV['GEM_PATH'] = File.join(Dir.pwd, 'gems')
puts Gem.dir
puts Gem.path

Now you can do your show adding or removing gems from there ;-)

HTH,
