           Bundler could not find compatible versions for gem "bundler": 
           In Gemfile: 
           rails (= 3.0.1) ruby depends on 
           bundler (~> 1.0.0) ruby 
           Current Bundler version: 
           bundler (1.1.rc.7) 
           This Gemfile requires a different version of Bundler. 
           Perhaps you need to update Bundler by running <code>gem install bundler</code>? 
     !
     !     Failed to install gems via Bundler.</p>
