This is coming from CXX.
I am not going to be able to figure out what the problem is, but those
who are (the C++ wizards) will probably want to see the full stack
trace, as well as the matplotlib version and the compilation parameters:
platform, compiler, python version, etc. The first part of the output
from setup.py build has all that.
