title: problems installing Pango-1.30.1
body: <p>I have encountered a problem installing Pango-1.30 on a Ubuntu 12.04 platform. During ./configure step I receive a message saying "Could not enable any of Freetype, X11, Cairo, or Win32 backends.  Must have at least one backend to build Pango".  However, I have build and installed Freetype and X11 and they are located in /usr/bin.  How do I inform ./configure where to get them?</p>
  
  <p>Thanks,
  Mark Allyn</p>
