Try a build with GCC-4.8

[chaubold]

• Make sure all dependencies obey the CXX=.. settings
• Boost compilation: https://schwartzmeyer.com/2014/04/18/boost-with-gcc-on-os-x/
• Qt configuration:
  • qt4-git/mkspecs/common/g++-base.conf: change gcc/g++ to gcc-4.8/g++-4.8
  • qt4-git/mkspecs/common/g++-macx.conf: remove -Xarch_x86_64 from QMAKE_CFLAGS_X86_64
  • ALTERNATIVE: compile Qt without STL
• VTK fixes:
  • remove -fpascal-strings from Utilities/ftgl/CMakeLists.txt
  • make sure VTK_REQUIRED_OBJCXX_FLAGS is not set to "" but is really not set at all, otherwise gcc thinks there are no input files
• update PGMLink and fix includes for strcpy etc

yapsy is not configured properly, cannot be imported, and thus the object classification workflows don't show up.

Yapsy problem can be fixed by:

cd to python2.7/site-packages
mkdir yapsy
cp -r Yapsy-1.10.2_pythons2n3-py2.7.egg/yapsy/* yapsy/

The futures egg is not included properly either. The solution is again to copy the futures and concurrent folders to site-packages.

For boost: following the link above, we need to add which gcc binary is used. We could either use basename which ${CMAKE_CXX_COMPILER}``, or try something like: http://stackoverflow.com/questions/14933172/how-can-i-add-a-minimum-compiler-version-requisite

Python fixes:

• rm -r Mac/PythonLauncher
• in Mac/Makefile remove the build and clean commands for PythonLauncher
