Robert, just so we're clear here. If one does a straight "setup.py
build" with numpy 1.0.1, do you get a version that uses Veclib? I do
understand that that is the Fortran-compatible version, and thus may
result in some extra copying to shift between row and column major
ordering. By the way, if one were to take care to use Fortran ordered
numpy arrays, would you avoid that copying?
On a few other topics in this thread:

Cost is not the issue -- I think the community is far better served if
there are a small ( ideally one ) number of places to go for Python
modules on OS-X. Ideally, it's possible to keep stuff in sync there too.

Not quite true. Bob has been out of town recently, and, indeed I have
volunteered to put stuff up there, but we've haven't coordinated that
yet. Bob -- can you give me permissions to put stuff up myself, or will
you be around enough for a while to keep doing it yourself?
He has been looking for someone to maintain the Wiki, but I don't think
I can do that.

I, for one, have spent quite a bit of time helping people out on this
mailing list and others, and have built packages and contributed them to
pythonmac as well.
As it happens, I haven't needed SciPy recently, so I haven't built it,
so I can't contribute it -- I hope to do so soon. However, I'm not sure
it's so unreasonable to ask someone that has gotten a great deal of help
on lists like this to then take the extra effort to put what they've
done up for others. I know I've tried to do that.

OK, this is a key problem. The truth is that we all have different
needs, and someone that has gotten numpy/MPL/SciPy all working for them
may not have a version that will work for everyone (Universal support,
working with TK and Wx, etc.)
So there does need to be a bit of testing and coordinating.
I hereby volunteer to do that. If someone things they have it all ready
to go, let me know, and I'll try to test and make sure that everything
fits together. From Robert's messages, I think I have a pretty good idea
what's possible. Again, this is what I think we should put up on pythonmac:
python 2.5 (I'm still on 2.4, but if someone is putting effort in, they
might as well do the latest)
All Universal and working together!
latest SciPy, built for the numpy above, linked to veclib. One each for
PPC and Intel.
Are there any other commonly used packages that need to be version
compatible with these?
