Given this environment:

    bash-2.05$ ATLAS=$HOME/src/ATLAS/lib/SunOS_gcc ; export ATLAS
    bash-2.05$ BLAS=$HOME/src/BLAS/sungcc ; export BLAS
    bash-2.05$ LAPACK=$HOME/src/LAPACK/Sun_GCC ; export LAPACK
    bash-2.05$ ls -lL $ATLAS
    total 13056
    -rw-r--r--   1 skip     skip        6181 Sep 23 10:57 Make.inc
    -rw-r--r--   1 skip     skip         739 Sep 23 10:57 Makefile
    -rw-r--r--   1 skip     skip     5722752 Sep 23 11:52 libatlas.a
    -rw-r--r--   1 skip     skip      290888 Sep 23 11:37 libcblas.a
    -rw-r--r--   1 skip     skip      343020 Sep 23 11:54 liblapack.a
    -rw-r--r--   1 skip     skip      279972 Sep 23 11:04 libtstatlas.a

Why doesn't scipy_distutils/system_info.py report the presence of any ATLAS
libraries?

    bash-2.05$ ~/tmp/sun_gcc/2.2/bin/python scipy_distutils/system_info.py
    atlas_info:
      NOT AVAILABLE

    blas_info:
      FOUND:
        libraries = ['blas']
        library_dirs = ['/home/skip/src/BLAS/sungcc']

    ...

    lapack_info:
      FOUND:
        libraries = ['lapack']
        library_dirs = ['/home/skip/src/LAPACK/Sun_GCC']

Thx,

Skip
