title: Can't install xdebug on Mac with Homebrew
body: <p>I'm kind of new to using Homebrew, but I love it.  It's so easy.  I'm trying install Xdebug.  Some of the posts on the web say to do this:</p>
  
  <pre><code>brew install xdebug
  </code></pre>
  
  <p>But it doesn't work.  I get: <code>Error, no available formula.</code>  </p>
  
  <p>I did <code>brew search xdebug</code> and it returned:</p>
  
  <pre><code>josegonzalez/php/php53-xdebug    josegonzalez/php/php54-xdebug
  </code></pre>
  
  <p>I tried several different iterations of <code>brew install</code> with this including <code>brew install php53-xdebug</code>, but still no luck.  Can someone help me?  I can't find anything on Xdebug's site about using Homebrew, but yet posts on the web seem to indicate it's possible.</p>
