title: what's the meaning of -bash PHPUnit command not found
body: <p>i have pear's phpunit installed (see image)</p>
  
  <p>I have that path in the include path (see image below) in php.ini. Note, other pear installations have worked with this include path, so I know there's nothing wrong with that path per see. </p>
  
  <p>Yet, when I'm trying to do a an example functional test with Yii , I move into the directory protected/tests/  and run this code (provided by a book I'm learning)</p>
  
  <pre><code> % cd protected/tests/ 
      % phpunit functional/SiteTest.php
  </code></pre>
  
  <p>I get told</p>
  
  <pre><code>-bash: phpunit: command not found
  </code></pre>
  
  <p>any idea what I'm doing wrong? </p>
