Respectfully disagree with the answer above. Here is how I do it:

ruby -S gem list my_gem

`*** LOCAL GEMS ***
my_gem (1.0.1, 1.0.0, 0.0.2)
`

ruby -S gem lock my_gem-1.0.0 > locklist.rb

which generates list of dependencies for a specific version into locklist

require 'rubygems'
gem 'my_gem', '= 1.0.0'
gem 'gem_base', '= 1.0.0'
gem 'rest-client', '= 1.7.2'
gem 'savon', '= 1.1.0'
gem 'addressable', '= 2.3.6'
gem 'mime-types', '= 1.25.1'
gem 'netrc', '= 0.11.0'

now you can do load('locklist.rb') which will load a specific version of a gem along with its dependencies. Look ma, no Bundler.
