Bundler could not find compatible versions for gem "torquebox-naming":
  In snapshot (Gemfile.lock):
    torquebox-naming (1.0.1)

  In Gemfile:
    torquebox depends on
      torquebox-naming (= 1.0.1)

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
