title: Artisan returns blank
body: <p>Whenever I run any <code>php artisan</code> command like <code>php artisan list</code>, I get nothing back. No commands work at all.</p>
  
  <p>I have been searching a little around, and have tried the following:</p>
  
  <ul>
  <li>changing permissions for <code>/root/.composer</code> to 777</li>
  <li>remove <code>bootstrap/compiled.php</code> file</li>
  </ul>
  
  <p>There is nothing in <code>app/storage/logs/log-cli-.txt</code>.<br>
  I can view the site in the browser.</p>
  
  <p>I'm running on CentOS 6.3 64bit with PHP v. 5.5.11 - Laravel 4.1</p>
