#36 Mac OS X build problems

[flip phillips]

Trying to build against Anaconda python distro on Mac OS 10.11
Using boost / scons as installed via

conda install boost
conda install scons

Building via the traditional

python setup.py install

gets me through a bunch of the compilation, (but, several warnings that are boost-in-origin) but then building wrappers/py_slots4.cpp

gcc -fno-strict-aliasing -I/Users/flip/anaconda/include -arch x86_64 -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -DBOOST_PYTHON_MAX_ARITY=18 -Isupportlib/include -I/System/Library/Frameworks/OpenGL.framework/Versions/A/Headers/ -I/Users/flip/anaconda/include/python2.7 -c wrappers/py_slots4.cpp -o build/temp.macosx-10.5-x86_64-2.7/wrappers/py_slots4.o

In file included from wrappers/py_slots4.cpp:6:
In file included from wrappers/py_slot.h:11:

so I'm sort of wondering if there is a boost or scons version issue here.
