  # First patch: The mini-Boost finder in FindCOLLADA doesn't find our boost, so fix it.
  # Second patch:
  # Lion replacement for CGDisplayBitsPerPixel();
  # taken from: http://www.openscenegraph.org/projects/osg/changeset/12790/OpenSceneGraph/trunk/src/osgViewer/DarwinUtils.mm
  # Issue at: https://github.com/mxcl/homebrew/issues/11391
  # should be obsolete with some newer versions (current version is: 3.0.1)
