One of our machines (OSX Intel) is already the buildbot slave for the
numpy buildbot. I think I can get us OK'd to build scipy on there as
well. We generate our own scipy builds so it shouldn't be too big a
problem. Unless there's an automated system, I'd prefer to to just
Some remaining issues:
- which SDK to build against. Leopard ships with a Python build
against the 10.5 SDK. It would be much easier, at least initially, for
us to produce binaries against the Leopard Python 2.5.
- how to deal with library dependencies such as fftw2. We currently
use MacPorts but I suppose it needs to be compiled statically or do we
just require that users install MacPort's fftw2?

It seems like scipy needs a buildbot.

It's relatively easy to build a single pkg for the entire scipy
distribution (that's what we do now) and put that on a DMG (as you
said). When scipy becomes a less monolithic package (i.e. using
setuptools namespace packages), we can create a pkg for each package
and a mpkg combining them all.
