I would like to do right by the deprecation warnings and suppress or silence them or whatever you might recommend as the best solution.
DEPRECATION WARNING: You have Rails 2.3-style plugins in
vendor/plugins! Support for these plugins will be removed in Rails
4.0. Move them out and bundle them in your Gemfile, or fold them in to your app as lib/myplugin/* and config/initializers/myplugin.rb. See
the release notes for more on this:
Ruby on Rails — Rails 3.2.0.rc2 has been released!.
