title: Unable to install Fabric on OSX using recommended Homebrew and pip. Xcode is latest version
body: <p>I've been trying for two days to figure this out now.  I have the latest version of OSX and Homebrew.  I followed a tutorial that had me install pip via Homebrew and then it was recommended to install Fabric from Homebrew with:</p>
  
  <pre><code>brew install Fabric
  </code></pre>
  
  <p>But the formula for Fabric is gone from Homebrew.  Yes, I ran an update too.  So I followed yet another tutorial that advised me to install via pip.  pip install fabric</p>
  
  <p>And it fails in all kinds of ways involving pycrypto.  Here's the pip log.  Aren't Macs supposed to make life easier?  </p>
