Thanks for the new include dirs and for the original patch.  They're
both now in CVS.  Since the default Mac OS-X non-vecLib build works
fine,  I'm going to wait a few weeks for 1.3.3.

I have related question though:  Should USE_LAPACK be the default for
Mac OS-X?  Is the vecLib framework is *always* there?    

Regards,
Todd
