That works, however: 

:info:configure -- Found PythonInterp: /usr/bin/python (found version "2.7.5") 
:info:configure -- Could NOT find PythonLibs: Found unsuitable version "2.7.8", but required is exact version "2.7.5" (found /opt/local/Library/Frameworks/Python.framework/Versions/2.7/Python)
:info:configure Python not found, install python!

There is a mismatch in versions as it's using the system installed python for PythonInterp. Do I have to enable this in the macports install?
