Just a note, you can check whether numpy built with this package is optimized utilizing openblas by checking whether numpy's lapack_lite library is linked with the openblas library:

$ ldd /usr/lib/python2.7/site-packages/numpy/linalg/
... => /usr/lib/

Of course running benchmarks would give you some idea as well.

numpy now requires openblas to be configured in site.cfg for it to be successfully compiled with openblas.

sftrytry and vidar, thanks for identifying the problem. I created a new src package with site.cfg included, but I have to shamefully admit I don't know how to successfully upload a src package to aur anymore with this new version. It complains that "Error - all directories must have permissions of 755", but I am pretty sure all files in and directory int the src package are either 644 or 755. I put the src package at dropbox for now:

How can I add cat command in PKGBUILD. I added your script above python2 stuff but got PKGBUILD syntax error of EOF.

2nd vidar.
I updated my numpy on May 17. It was not optimized.

Hello. There is a little flaw in the PKGBUILD. numpy is NOT automatically linked against openblas, I added this to the PKGBUILD just above the python2 lines and it worked:
(the standard prefix for my openblas-lapack package was /usr )

cat <<-EOF > site.cfg
libraries = openblas
library_dirs = /usr/lib
include_dirs = /usr/include

options=("staticlibs") required, packages like scipy won't build otherwise...

As compiling with openblas support is now handled upstream in numpy, this packages is only needed to indicate the dependency of openblas-lapack package (as openblas package doesn't do it) and do a build of numpy after openblas-lapack is installed.

Thank you, Xyne! I incorporated your changes in 1.7.1-5. Since @sftrytry created an openblas-lapack package, this package can now depend on the new package. I deleted my previous comment.

I am a bit ambivalent regarding separating PKGBUILD for python2 and 3. It is a pity that AUR doesn't support split package, but the single PKGBUILD works well on any archlinux box, and even though the python2 and 3 builds do not share any compilation, the commands are identical. So I am slightly leaning the current status - commenting out instead of removing the split package syntax.
