Comment #9 on issue 3008 by asmeu...@gmail.com: Cython (apparently) version
causing problems
http://code.google.com/p/sympy/issues/detail?id=3008
For me, Cython 0.15.1 causes an error, but 0.16 doesn't. I commented the
quiet flag in the code, and the error is
Traceback (most recent call last):

For another one Python version on my system that has 0.11.2, the errors are
things like

I think the first error (the CreateControlFlowGraph ImportError) is somehow
related to a bad configuration on my part, but I can't be sure.
At any rate, I can't figure out exactly what version we should be testing
for. Perhaps we should just XFAIL the test.
