Can't install bundler 1.3.0 with ruby 2.0

Question

I installed Ruby 2.0.0 and the compilation went fine but when I use bundle install it gives me this error:

Bundler is not compatible with Ruby 2.0 or Rubygems 2.0.
Please upgrade to Bundler 1.3 or higher.

If I try to update it with gem update bundler:

$ gem update bundler
Updating installed gems
Nothing to update

And when I try to update RubyGems:

$ gem update --system
Latest version currently installed. Aborting.

What am I missing?

I'm using Ruby 2.0.0-p0 & RVM 1.18.14.

Bundler 1.3 hasn’t been released yet, until it is you must install the prerelease version:

gem install bundler --pre
