It works!

Setup for “vendored gem”:
In enviroment.rb add the gem:
config.gem “timcharper-calendar_date_select”, :version => “1.11”, :source => “http://gems.github.com”, :lib => ‘gem_init’

Install the gem locally (this installs the gem system wide)
sudo rake gems:install

Unpack the gem locally (this unpacks it vendor/gems/ inside your applicatio)
rake gems:unpack

Remove the system wide gem (this is require until Ticket#324 is closed [http://rails.lighthouseapp.com/projects/8994/tickets/324-gem-dependencies-inconsistently-load-rails-init-rb])
sudo gem uninstall artmotion-calendar_date_select

Don’t forget to include the javascript helper in your view:
<%= javascript_include_tag :defaults >
<= calendar_date_select_includes %>
