[SciPy-user] Where do I put site.cfg? What should it contain? Can I build w/o atlas?

[skip at pobox.com]

I'm trying to build numpy an svn sandbox (just updated a couple minutes
ago).  If I grub around in numpy/distutils/system_info.py it says something
about creating a site.cfg file with (for example) information about locating
atlas.  It says nothing about where this file belongs.  I took a stab and
placed it in my numpy source tree, right next to setup.py, with these lines:

    [atlas]
    library_dirs = /home/titan/skipm/src/ATLAS/lib/SunOS_Babe
    include_dirs = /home/titan/skipm/src/ATLAS/include/SunOS_Babe
    # for overriding the names of the atlas libraries
    atlas_libs = lapack, f77blas, cblas, atlas

I then verified that those directories exist, contain apparently useful
contents, and that I didn't have a conflicting environment variable named
ATLAS:

    % ls /home/titan/skipm/src/ATLAS/lib/SunOS_Babe
    Make.inc       libatlas.a     libf77blas.a   libtstatlas.a
    Makefile       libcblas.a     liblapack.a
    % ls /home/titan/skipm/src/ATLAS/include/SunOS_Babe

    atlas_cacheedge.h   atlas_dmvS.h        atlas_ssysinfo.h
    atlas_ztrsmXover.h
    atlas_cmv.h         atlas_dmvT.h        atlas_strsmXover.h  cXover.h
    atlas_cmvN.h        atlas_dr1.h         atlas_trsmNB.h      cmm.h
    atlas_cmvS.h        atlas_dsysinfo.h    atlas_type.h        dXover.h
    atlas_cmvT.h        atlas_dtrsmXover.h  atlas_zNCmm.h       dmm.h
    atlas_cr1.h         atlas_sNCmm.h       atlas_zmv.h         sXover.h
    atlas_csysinfo.h    atlas_smv.h         atlas_zmvN.h        smm.h
    atlas_ctrsmXover.h  atlas_smvN.h        atlas_zmvS.h        zXover.h
    atlas_dNCmm.h       atlas_smvS.h        atlas_zmvT.h        zmm.h
    % env | grep ATLAS
    %

Then I tried "python setup.py build":

How come distutils is ignoring my site.cfg file?  Neither of these commands:

    python setup.py --help
    python setup.py build --help

mention site.cfg.

Failing all this, is there some way to build numpy/scipy without atlas?  At
this point I just want the damn thing to build.  I'll worry about
performance later (if at all).

Thx,
