[Numpy-discussion] building NumPy with Intel CC & MKL

I'm trying to build NumPy on an SUSE 10.2 Core 2 Duo system using the
Intel compiler and Math Kernel Library, and Python 2.5

I want to see how much faster it is than the SUSE NumPy 1.0.1 rpm that
recently became available (huge thanks to whomever it was that created
it. Installing NumPy and SciPy has been a lot of work on SUSE systems in the
past. Half the time I'd give up in frustration after hours of work with
each new distribution, and wait until the next SUSE release and try

I followed the instructions that are here:


Any distribution with Intel C compiler and MKL

I changed the line:
cc_exe = 'icc -O2 -g -fomit-frame-pointer -mcpu=pentium4 -mtune=pentium4 -march=pentium4 -msse2 -axWN -Wall'
cc_exe = 'icc -O2 -g -fomit-frame-pointer -mcpu=pentium4 -mtune=pentium4 -march=pentium4 -msse3 -xP -Wall'

But the NumPy compile failed:

Running from numpy source directory.

There is no config directory in /usr/lib/python2.5/ 
These are the subdirectories:

The only Makefiles under Python2.5 are:

Help anyone? I hope I don't have to build Python2.5 from source to build NumPy.
