I already logged it on SF.

I was planning to have two lists of libraries, with Absoft commented out
this time around since it is a commercial compiler.  The second (active)
list would be the one for g77.

Yes.

I think you were right earlier.

I added --use_lapack,  as in 'python setup.py install --use_lapack'.

One thing I noticed was that I didn't appear to need cblas.  Comments?

We more or less crossed e-mails.  I saw your later comments about
eliminating Absoft library list altogether but don't think that is
necessary;  I think hints from other people's installations are useful
so unless there's something wrong with the Absoft list,  I think we
should leave it in, but with g77 as the default.
