Does not install on ubuntu 14.04

Bundler could not find compatible versions for gem "bundler":
In Gemfile:
bundler (~> 1.5) ruby

Current Bundler version:
bundler (1.3.5)

This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running gem install bundler?

Upgrading bundler prepends the new version in the bundler list but it still tries to run 1.3.5.
