Bug 257400: science/py-scipy add option for Atlas blas
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=257400



--- Description ---
Not sure I made the git diff correctly, getting used to this, and hacking as I
go, so I will also submit all the individual files. I took the basic Makefile
framework from py-numpy and tweaked it so it would be appropriate for py-scipy.
I tried to do netlib as well, but while it seemed to configure to use the right
libraries the final package had a dependency on atlas-math. I didn't dig to
hard to find why, but I suspect it is because the build notes for scipy say
they will default built against Atlas if found as presumably the preferred
blas. As I doubt anyone would be using netlib with this package, I opted to
limit things to Atlas and OpenBLAS. The issue is I have no way to test the
OpenBLAS is still working ok, but I can confirm the Atlas build is fine, and am
using it to build towards qgis ultimately. I believe the OpenBLAS case should
work as it is the same mechanism of numpy, which seems to be the master library
to scipy if I'm reading things right. Would be great to get this patch to allow
Atlas as well.
