title: PHPUnit failed opening required file
body: <p>I've browsed through similar problems on SO, but to no avail. I'm running PHP 5.3.6 and phpunit version 3.6.10. When attempting to execute a simple test:</p>
  
  <pre><code>require_once 'PHPUnit/Framework.php';
  
  class UserTest extends PHPUnit_Framework_TestCase {
  }
  </code></pre>
  
  <p>I receive the following error:</p>
  
  <pre><code>PHP Fatal error: require_once(): Failed opening required 'PHPUnit/Framework.php'
  (include_path='.:/Users/username/pear/share/pear:/usr/lib/php/pear/:/Users/username/pear/share/pear/PHPUnit') in ...
  </code></pre>
  
  <p>When reinstalling PHPUnit, I'm not sure if the install location was duplicated, but it appears that when running <code>which phpunit</code>, the path is: <code>/usr/bin/phpunit</code>. However, it appears to also be installed in <code>/Users/user/pear/bin/phpunit</code>. 
  I've tried updating all channels and reinstalling PEAR and PHPUnit, but the problem still exists. I'm running on OSX Lion. Any help would be greatly appreciated.</p>
