Thanks very much for tracing the problem down. One option is that we simply add
a patch to the Debian package to rewrite /usr/bin/python back to
/usr/bin/env python.
I can do this when uploading a new version of cython.

So what is the solution to fix this? Fixing the cython's setup.py? Let's do that
in the next release then.

Fixing the Debian is just a temporary solution, so that we have it working now.
