15:57:11 CMake Error at /opt/local/share/cmake-3.2/Modules/FindPackageHandleStandardArgs.cmake:138 (message): 15:57:12 Could NOT find PythonLibs: Found unsuitable version "2.7.5", but required 15:57:12 is at least "3.4.3" (found PYTHON_LIBRARY-NOTFOUND)
The OSX builders have as of now python 2.7.10 and 3.4.3 installed. The base system offers also three versions 2.[5-7]...
So, in order to run python version 3.4 one needs to access /opt/local/bin/python3.4, which is probably not done by this job...
