Given:
scipy-0.6.4
numpy 1.0.4
python 2.5.1
AIX 5.3
xlc v8
xlf v10
essel 4.2
lapack 3.1.1 with CCI


Problem:
During the scipy build - python setyp.py build  - the following error shows up:
....

I found a reference regarding the IBM XLF  compiler running on mac
http://projects.scipy.org/pipermail/scipy-user/2004-May/002884.html 

where Pearu says:
... it turns out  that -D/-U options to xlf compiler are not for defining cpp macros...

The following information from the xlf Compiler says regarding the -D option :
...
-D     Specifies whether the compiler compiles fixed
                source form lines with a D in column 1 or treats
                them as comments. Please note that in order to pass
                C-style -D macro definitions to the C preprocessor
                (e.g. compiling a file that ends with .F) use the
                -W option. For example:
                -WF,-DDEFINE_THIS
                -D is the short form of -qdlines
...
-U     Makes the compiler case-sensitive to identifier
                names. By default the compiler interprets all names
                as if they were lower-case.

Solution: 
Changeing the Command line from :
/usr/bin/xlf -qextname -O5 -DNO_ATLAS_INFO=1 ....../fblas-f2pywrappers.o
to 
/usr/bin/xlf -qextname -O5 -WF,-DNO_ATLAS_INFO=1 .... /fblas-f2pywrappers.o

allowed the command line to succed without an error. But i do not know if the -WF,DNO_ATLAS_INFO=1 will change the program logic nor where to change ( in case the -WF, is the solution ) this permanently.
The only reference i found regarding -DNO_ATLAS_INFO=1 was within the file: ../site-packages/numpy/distutils/system_info.py
