title: Unable to build mercurial on OSX - Python.h not found
body: <p>For what I've read I need Python-Dev, how do I install it on OSX?</p>
  
  <p>I think the problem I have, is, my Xcode was not properly installed, and I don't have the paths where I should. </p>
  
  <p>This previous question: </p>
  
  <p><a href="https://stackoverflow.com/questions/2685887/where-is-gcc-on-osx-i-have-installed-xcode-already">Where is gcc on OSX? I have installed Xcode already</a></p>
  
  <p>Was about I couldn't find gcc, now I can't find Python.h</p>
  
  <p>Should I just link my /Developer directory to somewhere else in /usr/ ??? </p>
  
  <p>This is my output: </p>
