Please, no. Building should not involve any internet connection. This
can fail in so many ways, we will get many reports of people with weird
network policies and so on. And OS packagers will hate us even more.

Cython becomes a build dependency, it should be checked and handled as
such. I will add numpy.distutils support  to make this transparent
(unless someone beats me to it).
