title: Installing gmpy on OSX - mpc.h not found
body: <p>I have <code>brew install</code>ed <code>mpc</code>and <code>gmp</code> , but when I try to <code>pip install gmpy2</code> I get a compile error on the line</p>
  
  <pre><code>#include "mpc.h"
  </code></pre>
  
  <p>so for some reason <code>clang</code> is having trouble finding the <code>mpc</code> library. I'm not sure what I should do at this point.</p>
