Are you freezing your apps before deploying them? Adding the appropriate version in your environment.rb is good but, you also need to freeze your apps so it deploys with it's version of Rails.
Very simple to do, just use the Rake command and add the version you want to freeze to. The last might not be needed as it should be piccked up from the environment.rb but it couldn't heard.
rake rails:freeze:gems VERSION=2.1.3
