Incompatible with Rails 3 bundler

[contentfree]

When running bundle install with Rails edge and the current restful_authentication from gemcutter, it fails with:

No compatible versions could be found for required dependencies:
    Conflict on: "rails":
    * rails (3.0.0.beta1) activated by rails (>= 0, runtime)
    * rails (~> 2.3.4, runtime) required by restful_authentication (>= 0, runtime)
    All possible versions of origin requirements conflict.
