Resolving dependencies...
Bundler could not find compatible versions for gem "activesupport":
In snapshot (Gemfile.lock):
activesupport (3.2.12)
In Gemfile:
rails (= 3.2.13) ruby depends on
activesupport (= 3.2.13) ruby
Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
