title: PHPUnit installed but simply doing nothing
body: <p>I am following along with the tutorials in 'Easy PHP Websites with Zend Framework' and wanted to install PHPUnit.</p>
  
  <p>System: Mac OS x Lion, PHP running locally (Not MAMP)</p>
  
  <p>Pear was installed and working fine, I upgraded it to the latest.</p>
  
  <p>Installed PHPUnit using</p>
  
  <pre><code>sudo pear install phpunit/PHPUnit
  </code></pre>
  
  <p>terminal did some work and installed it without errors</p>
  
  <p>The in my terminal I did </p>
  
  <pre><code>phpunit --version
  </code></pre>
  
  <p>this returns/does nothing as follows (Username removed)</p>
  
  <pre><code>Machine:~ Username$ phpunit --version
  Machine:~ Username$ sudo phpunit --version
  Machine:~ Username$ 
  </code></pre>
  
  <p>Was worried it some how did not install so I check for the PHPUnit files and they do exist under /usr/lib/php/phpunit</p>
  
  <p>Also checked that the phpunit exe exists which it does under /usr/bin</p>
  
  <p>edited .profile as well as .bash_profile to include the /usr/bin path to have</p>
  
  <pre><code>export PATH=/usr/bin:$PATH
  </code></pre>
  
  <p>then restarted terminal</p>
  
  <p>running </p>
  
  <pre><code>echo $PATH
  </code></pre>
  
  <p>shows</p>
  
  <pre><code>/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/git/bin:/Users/xxxxx/development/frameworks/ZendFramework-1.11.11/bin
  </code></pre>
  
  <p>php.ini includes is</p>
  
  <pre><code>include_path = ".:/usr/lib/php/pear:/Library/Server/Web/Data/Sites/ZendFramework-1.11.11/library"
  </code></pre>
  
  <p>Where xxxxx is my username on the Mac</p>
  
  <p>even going into /usr/bin in terminal and using phpunit --version returns nothing</p>
  
  <p>in case its relevant my PEAR config shows</p>
  
  <pre><code>Configuration (channel pear.php.net):
  =====================================

  PEAR www files directory       www_dir          /usr/lib/php/htdocs
  ....
  </code></pre>
  
  <p>Also added the pear and phpunit directory to my php.ini includes path list.</p>
  
  <p>Am at a loss as to why this does not want to work. Am sure its me and I have done something incorrectly....Any help appreciated.</p>
