Hello,

I've added this buildpack as stated on the readme, but it fails to build the gem "prawn-gmagick". Here is the log

This buildpack installs the graphicsmagick binaries but does not install the development libraries to compile against. The easiest way to get them would probably be installing the libgraphicsmagick1-dev package via apt using https://github.com/ddollar/heroku-buildpack-apt
