[vtkusers] VtK 7, python3.4 build error

[Matthew Cragun]

I am having trouble building VTK 7 with Python 3.4 on OS X 10.11 .
Everything goes well for the first 99% of the process, however at the end,
I get this error:

Similar errors are repeated until...

Any thoughts on what I missed?  Are there pre-built binaries with python 3
for OS X?

Thanks,

Matt
