[Numpy-discussion] Trouble installing Numpy on AIX 5.2.

[mfmorss at aep.com]

I built Python successfully on our AIX 5.2 server using "./configure
--without-cxx --disable-ipv6".  (This uses the native IBM C compiler,
invoking it as "cc_r".  We have no C++ compiler.)

But I have been unable to install Numpy-0.9.5 using the same compiler.
After "python setup.py install," the relevant section of the output was:

compile options: '-Ibuild/src/numpy/core/src -Inumpy/core/include
-Ibuild/src/numpy/core -Inumpy/core/src -Inumpy/core/include
-I/pydirectory/include/python2.4 -c'

A closely related question is, how can I modify the Numpy setup.py and/or
distutils files to enable me to control the options with which cc_r is
invoked?  I inspected these files, but not being very expert in Python, I
could not figure this out.
