What I'm trying to accomplish:
- Updating Bundler version from 1.0.22 to 1.3.0 so it's compatible with Rails 4,
and then updating to Rails 4.0.0.beta1

Command I ran:
- gem update bundler (successfully installed bundler 1.3.0)
- bundle update rails (to 4.0.0.beta1 in gemfile)

What I expected to happen:
- For the rails gem to be updated
