Michael thanks for your help on building 64-bit python/numpy.     I followed
your instructions, and was able to build the python portion.  (I did the
test "python -c 'import platform;print platform.architecture()' "  suggested
by Jon and I got the 64-bit result, so I think it worked properly.)
Thanks very much for this!   However, I was unable to get the numpy build to
work.   When running the setup.py install, I get all sorts of permission
errors, so I'm forced to run it as su.  (Is this a bad idea?)     Anyhow,
when I do run "sudo python setup.py install" in the numpy-1.1.0 directory I
downloaded from SciPy website, the build apparently works.  But when I go
into python, I'm not able to import numpy.  Specifically, I get:

   daniel-yaminss-mac-pro:Desktop danielyamins$ python
   Python 2.5.2 (r252:60911, Jun  5 2008, 19:13:50)
   [GCC 4.0.1 (Apple Inc. build 5465)] on darwin
   Type "help", "copyright", "credits" or "license" for more information.
   >>> import numpy
  Traceback (most recent call last):

       import multiarray
  ImportError:

no suitable image found.  Did find:
      /usr/local/lib/python2.5/site-packages/numpy/core/multiarray.so: no
matching architecture in universal wrapper


Does anyone know what this error means, and/or how to fix it?   Sorry if
it's obvious and I should know it alread.y


Thanks!
Dan
