rails--rails/railties/lib/tasks/gems.rake
David Dollar 99d75a7b02 Makes the gem system understand development vs. runtime dependencies [#2195 state:resolved]
The patch also fixes:

* Fixes the chicken/egg problem present in the current gem system when
  gems are defined in the config that are not yet installed.

* Remove the need to have hoe as a dependency of your production app.

* Makes the gem 'unpacking' system a lot less fragile.
