Hi Gregory,

The error you describe seems to be due to some mixup of 32 and 64 bits. 
I was not able to find out exactly why it happens on Mac OS Yosemite, 
before there were no problems on Mac OS.

The following helped me fix the problem by explicitly stating I want to 
compile for 64 bits (it's the ARCHFLAGS parameter which does the job, 
adapt the other parts to your needs):

sudo ARCHFLAGS="-arch x86_64" python3 setup.py build_ext --inplace -j4

Hope this helps,
