title: Rails shoulda and factory_girl setup
body: <p>I have installed both shoulda and factory_girl, I can run shoulda just fine, but when I add this:</p>
  
  <pre><code>require 'factory_girl'
  
  Factory.define :user do |u|
    u.mail 'test@example.com'
    u.pass 'secret'
  end
  </code></pre>
  
  <p>to my test/test_helper.rb I'm getting this error:</p>
  
  <p>/test/test_helper.rb:1:in `require': no such file to load -- factory_girl (LoadError)</p>
  
  <p>when I execute rake test:units</p>
  
  <p>I have installed both gems using:</p>
  
  <p>sudo gem install thoughtbot-shoulda --source=<a href="http://gems.github.com" rel="nofollow noreferrer">http://gems.github.com</a>
  sudo gem install thoughtbot-factory_girl --source=<a href="http://gems.github.com" rel="nofollow noreferrer">http://gems.github.com</a></p>
  
  <p>and can see both of them being installed fine.</p>
  
  <ul>
  <li>And by the way, this works fine as well:</li>
  </ul>
  
  <p>script/console
  Loading development environment (Rails 2.3.8)</p>
  
  <blockquote>
    <blockquote>
      <p>require 'factory_girl'
      => []</p>
    </blockquote>
  </blockquote>
  
  <p>so requiring the gems seems to be working</p>
