My point was that it's nice to be able to have it build with an out of
teh box wetup.py with accelerated LAPACK and all... If whoever is
building binaries wants to get fancy, great.

oh well, not on 10.8 yet myself -- if it's broken, it's broken :-(

Maybe, but stand alone scripts like that get pretty fragile ( I know,
I have a few of them myself...)  I really want to have a better system
in place to build binaries for the mac -- ideally a system that uses
the same infrastructure to build a variety of Mac packages, rather
than each package having it's own build scripts that need to be
maintained and  probably overlap with each other.

I"m looking at gattai as a system to build on.
(http://sourceforge.net/projects/gattai/)

There is also the issue of third-party dependencies (libpng,
libfreetype, blas, etc, etc) I kind of like how Anaconda appears to be
doing it. They have packages that have the shared libs in them, and
then other packages can depend on those.

Anyway, lots to do!
