title: rails 3 using folder name as namspace throws uninitialized constant error
body: <p>I'm trying to upgrade an app <strong>from rails 2.3 to 3.0</strong> and it has a file </p>
  
  <pre><code>app/utility/interface/import/import_statistics_manager.rb
  </code></pre>
  
  <p>which contains</p>
  
  <pre><code>class Utility::Interface::Import::ImportStatisticsManager         
  //code here  
  end
  </code></pre>
  
  <p>I beleive <code>Utility::Interface::Import</code> are the folder names in its file path but used as namespaces </p>
  
  <p>This code works fine in rails 2.3 but when I try to run with rails 3.0.6 it throws a NameError</p>
  
  <pre><code>Error message:
     uninitialized constant Utility
  Exception class:
     NameError
  </code></pre>
  
  <p>FYI: rails 2.3 uses ruby 1.8.7 and rails 3.0.6 uses ruby 1.9.2 </p>
  
  <p>Please correct me if my understandings are not correct</p>
