Comment (by mmoll@…):

 Maybe that's all that needs to built. Notice that the files it compiles
 are called */all_files.cpp. I was under the impression that due to the
 heavy use of meta-template programming CGAL is mostly header-only. I have
 successfully compiled and install py34-graph-tool, another port that
 depends on CGAL. This update is nor urgent as far as I am concerned. If
 you don't think this is working correctly, you can hold off on committing
 it.
