title: Include path problems installing PEAR/PHPUnit
body: <p>I'm following this <a href="http://www.newmediacampaigns.com/page/install-pear-phpunit-xdebug-on-macosx-snow-leopard" rel="noreferrer">http://www.newmediacampaigns.com/page/install-pear-phpunit-xdebug-on-macosx-snow-leopard</a> to install PEAR/PHPUnit. I'm having trouble with the include paths.</p>
  
  <p>Some background info:</p>
  
  <pre><code>Farooqs-MacBook-Pro:bin fyousuf$ which php
  /usr/bin/php
  
  Farooqs-MacBook-Pro:bin fyousuf$ which pear
  /usr/local/bin/pear
  
  Farooqs-MacBook-Pro:bin fyousuf$ which phpunit
  /usr/local/bin/phpunit
  </code></pre>
  
  <p>I think the part where I'm messing up is "Update PHP include path" in the link I posted above.</p>
  
  <p>This is what is in my php.ini file:</p>
  
  <pre><code>    ; UNIX: "/path1:/path2"
      ;include_path = ".:/php/includes"
      include_path = ”/usr/local/bin/PEAR:/php/includes”
      ;
      ; Windows: "\path1;\path2"
      ;include_path = ".;c:\php\includes"
      include_path = ”/usr/local/bin/PEAR:/php/includes”
      ;
      ; PHP's default setting for include_path is ".;/path/to/php/pear"
      ; http://php.net/include-path`
  </code></pre>
  
  <p>When I try to run a Selenium test using phpunit I get this error:</p>
  
  <pre><code>   phpunit functions.php
  
     PHP Warning:  require_once(File/Iterator/Autoload.php): failed to open stream: No such            
     file or directory in /usr/local/pear/share/pear/PHPUnit/Autoload.php on line 64
     PHP Fatal error:  require_once(): Failed opening required 'File/Iterator/Autoload.php'         
     (include_path='”/usr/local/bin/PEAR:/php/includes”') in       
     /usr/local/pear/share/pear/PHPUnit/Autoload.php on line 64
  </code></pre>
  
  <p>New Edits:</p>
  
  <p>I have PHPUnit installed:</p>
  
  <p>Farooqs-MacBook-Pro:echo360-5.0 fyousuf$ sudo pear install phpunit/PHPUnit
  phpunit/PHPUnit is already installed and is the same as the released version 3.7.27
  install failed</p>
  
  <p>But when I type phpunit in terminal I get the same error as before:</p>
  
  <p>PHP Warning:  require_once(File/Iterator/Autoload.php): failed to open stream: No such file or directory in /usr/local/pear/share/pear/PHPUnit/Autoload.php on line 64
  PHP Fatal error:  require_once(): Failed opening required 'File/Iterator/Autoload.php' (include_path='.:/usr/local/PEAR:/php/includes') in /usr/local/pear/share/pear/PHPUnit/Autoload.php on line 64</p>
