I think Cython has some pre-made distutils hooks to make this less
painless. I don't know how nicely they work with numpy.distutils,
however...

A bigger issue than build setup may be that then we'd require users to
have the latest Cython installed to build Scipy. (Perhaps the
generated .c files could be shipped with the distributed tarballs,
though, so only people interested in SVN would need Cython.)
Actually, this might not be so much to ask, given that Cython is a
pure-Python package.

So, should we make Scipy depend on Cython at build-time?

I agree that things may get annoying if we decide to avoid this in the
long run, if the number of Cython-based extensions starts to grow.
