title: /usr/include folder missing in mac
body: <p>I've tried pretty much everything on stackoverflow and other forums to get the /usr/include/ folder on my mac (currently using OS X 10.9.5)</p>
  
  <ol>
  <li>Re-installed Xcode and command line tools (actually, command line tool wasn't one of the downloads available - so I'm guessing it's was already downloaded)</li>
  <li>tried /Applications/Install Xcode.app command line on terminal</li>
  </ol>
  
  <p>I haven't tested if there is no standard library on Xcode, but I'm only trying to build cloudera/hue from github and it won't install because there is no /usr/include/python2.7 (and couldn't really ask their forum because the error isn't coming from cloudera/hue).</p>
  
  <p>How do I get the /usr/include folder?</p>
