Thanks for the cogent response Fransesc. It's nice to know when
you're up against a "Really Hard Problem", rather than just missing
something obvious. I've started reading Ulrich Drepper report, and it
looks like a great place to start.
Cheers,

Okay, nevermind. I was able to install using the Superpack, even
though I'm using MacPython (ActivePython is supposedly required).

Hi everyone,
I'm trying to install numpy and scipy on my Mac that runs OS X 10.4.
It looks like my only option is to use the subversion copies. After
running "python setup.py install" in the numpy directory, it seems to
install, despite some error messages tucked away in the middle of the

Did you edit site.cfg to use optimised libraries (ATLAS, MKL, whatever)?

Hi all,
for my calculations, I need multi-precision arithmetics. For this, I use the
wonderful Python-only mpmath (http://code.google.com/p/mpmath/) and store and
handle my data in Numpy arrays. I thus have Numpy arrays with dtype=object
holding mpmath objects.
Now, some of the array operation

Can't you ask your admin to install rpm packages ? Uncompressing the rpm

Has anyone tried mixing numpy with stackless? I am wondering if there
are any obvious reasons why it would not work. I am thinking
specifically of issues that may arise using the stackless microthreads.
