[SciPy-User] recipe for installation on Mac OS X?

[Ben Willmore]

Hi,

I'm trying to install scipy on Mac OS X 10.6 and have not succeeded
after a fair bit of effort. I wonder if anyone can provide some
guidance.

I have tried:

1. Apple's Python 2.6 and the SciPy superpack from
<http://stronginference.com/scipy-superpack/>
-- scipy.test('1','10') fails with errors relating to ARPACK, such as [1].

2. python.org Python 2.7, gfortran and the compilation instructions
from <http://www.scipy.org/Installing_SciPy/Mac_OS_X>
-- scipy.test('1','10') fails; I didn't store the error.

3. python.org Python 2.7, and corresponding prebuilt SciPy/NumPy
binaries from <http://www.scipy.org/Download>
-- scipy.test('1','10') fails with errors relating to Weave, e.g. [2].

4. plus a number of less well defined approaches, none of which has
resulted in a SciPy that passes tests.

Can anyone tell me what I've done wrong with the above, or provide a
different strategy for successful installation of a recent SciPy on
Mac OS X. I am non-naive about compilers etc and willing to put in a
bit of effort to get this working satisfactorily.

Thanks for any advice!

Ben
