title: Rails 3's "bundle install" is super fast (takes 1 second), but no Rails is there afterwards? (using rvm)
body: <p>I am using rvm, doing the following:</p>
  
  <pre><code>rvm install ree    &lt;--- (Ruby Enterprise Edition), or this can be 1.8.7 or 1.9.2
  rvm ree
  rvm gemset create 'proj'
  cd path/to/proj
  bundle install
  </code></pre>
  
  <p>so Gemfile in that project says:</p>
  
  <pre><code>gem 'rails', '3.0.0'
  </code></pre>
  
  <p>and <code>bundle install</code> is super fast, reporting</p>
  
  <pre><code>Using rails (3.0.0) 
  </code></pre>
  
  <p>but after that when I type</p>
  
  <pre><code>$ rails -v
  /Library/Ruby/Site/1.8/rubygems.rb:779:in `report_activate_error': Could not find RubyGem rails (&gt;= 0) (Gem::LoadError)
      from /Library/Ruby/Site/1.8/rubygems.rb:214:in `activate'
      from /Library/Ruby/Site/1.8/rubygems.rb:1082:in `gem'
      from /usr/bin/rails:18
  
  $ which rails
  /usr/bin/rails
  </code></pre>
  
  <p>so <code>bundle install</code> doesn't install the rails as a gem?
  but if I type <code>script/rails -v</code> it shows it is 3.0.0</p>
