Build Error

I ran into the following compilation error when building the Cython component of Quartz:

ubuntu@ip-172-31-72-27:~/quartz/python$ python setup.py build_ext --inplace install
Compiling quartz/_cython/core.pyx because it changed.

Any hints on how to fix it?

What's the Cython version? Is it the code on master branch?
