title: Heroku fails to perform clockwork delayed tasks
body: <p>I am having a clockwork configuration file(inside the lib folder) that queues another file's methods to perform delayed tasks.</p>
  
  <pre><code>require_relative "Adwords/Extractor"
  </code></pre>
  
  <p>It is working fine on my local machine (WEBrick running on win8). However on heroku, it is failing with the following error:</p>
  
  <pre><code> 'app[web.1]: /app/lib/clock.rb:5:in `require_relative': cannot load such file -- /app/li
    b/Adwords/Extractor (LoadError)'
  </code></pre>
  
  <p>The Extractor.rb script is located at the same place as mentioned by the error statement.</p>
