RubyGems 2.0 includes several new features and many breaking changes.
Some of
these changes will cause existing software to break. These changes are
result of improvements to the internals of RubyGems that make it more
maintainable and improve APIs for RubyGems users.

If you are using bundler be sure to install a 1.3.0.prerelease version
newer. Older versions of bundler will not work with RubyGems 2.0.
