I'm trying to install the package grako from PyPI which apparently compiles stuff with Cython. I don't know what this process means and it breaks with an unresolved symbol.
Maybe someone can give me a hint what to check for to make this work?
Here is the output on Windows, Anaconda, Python 3.4:

It says

Is there a simple way I can fix that?
This is bug 52 against Grako.
Upgrading to version 3.6.1 should solve the problem.
