What version of Cython do you have installed?
cython -V

I just ran into the same problem installing it on Wheezy. The version installed with Wheezy is 0.15.1
You can upgrade to this version manually
https://packages.debian.org/wheezy-backports/armhf/cython/download

or install with pip
pip install cython --upgrade
