title: Ruby refinements not working in CI server
body: <p>I'm having errors within the Jenkins server:</p>
  
  <pre><code>$ ruby -v
  ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-linux]
  </code></pre>
  
  <p>When running rspec, I have the following error:</p>
  
  <pre><code> undefined method `using' for #&lt;Class:0x000000026f9c88&gt; (NoMethodError)
  </code></pre>
  
  <p>the exact same code works on my local computer, with ruby2. 
  Here's my version: <code>ruby 2.0.0dev (2012-12-01 trunk 38126) [x86_64-linux]</code>
  Also, it works on irb. It seems that ruby isn't recognizing the <code>using</code> statement when running a script.</p>
  
  <p>Here's the code:</p>
  
  <pre><code>describe "blah" do
      include TestHelper
      using TestHelper::BrowserRefinement
      ...
  end
  </code></pre>
  
  <hr>
  
  <p>clarification: <strong>the refinement is defined in a different file.</strong> I'm scourging the interwebs to see if there's a difference between revisions <code>r39474</code> and <code>r38126</code>.</p>
