I added omniauth gem to my gemfile and tried to run bundle install, but got a message about incompatibility of rails and bundler versions. I tried to update rails, but got messages about incompatibility with other gems. How can I downgrade bundler to 1.0?

$ bundle install

Bundler could not find compatible versions for gem "bundler":
  In Gemfile:
    rails (= 3.0.0) ruby depends on
      bundler (~> 1.0.0) ruby

  Current Bundler version:
    bundler (1.1.1)

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

和

$ bundle update rails

    bundler (1.1.1)
