Rails 4 deploy fails

[hakongit]

Push with heroku_san gives:
Everything up-to-date
git update-ref -d refs/heroku_san/deploy
Your Ruby version is 1.9.3, but your Gemfile specified 2.0.0
Your Ruby version is 1.9.3, but your Gemfile specified 2.0.0
rake aborted!
Command failed with status (18): [heroku run rake db:migrate --app application]

Somehow heroku_san thinks I have ruby 1.9.3 and rake db:migrate fails.

When I run heroku run rake db:migrate --app application manually it works fine.

It's the same problem as #151 -- sadness
