Thanks, that blocked setup.py from getting the wrong libs but nothing I
do seems to get scipy installed.

I had to modify site.cfg:
[DEFAULT]
library_dirs = /ul/zollars/lib
include_dirs = /ul/zollars/include
because setup continued to find the bad libs when the default system lib
directories were listed.  Will this be a problem?

[atlas]
library_dirs = /ul/zollars/opt/ATLAS/lib/Linux_g77_32
atlas_libs = lapack_g77_32, f77blas_g77_32, cblas_g77_32,atlas_g77_32
I am getting this with setup.py install:

gcc -pthread -shared
build/temp.linux-ppc64-2.4/build/src/atlas_version_-0x74e85a32.o
-L/ul/zollars/opt/ATLAS/lib/Linux_g77_32 -latlas_g77_32 -o
build/temp.linux-ppc64-2.4/atlas_version.so
  FOUND:
    libraries = ['lapack_g77_32', 'f77blas_g77_32', 'cblas_g77_32',
'atlas_g77_32']
    library_dirs = ['/ul/zollars/opt/ATLAS/lib/Linux_g77_32']
    language = c
    define_macros = [('ATLAS_INFO', '"\\"3.4.2\\""')]
 
lapack_opt_info:
atlas_threads_info:
scipy_distutils.system_info.atlas_threads_info
scipy_core/scipy_distutils/system_info.py:598: UserWarning:
*********************************************************************
    Could not find lapack library within the ATLAS installation.
*********************************************************************

I built the full lapack library according to the instructions with
ATLAS.  What else can I check?

I have also tried setting the $BLAS and $LAPACK variables which do lead
to a successful scipy install, but then fails the
t=scipy.test(level=1).  In this case the errors indicate problems with
the scipy.linalg module, further suggesting problems with LAPACK.  But I
don't know what else to check.

Any suggestions?
Eric
