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.

It seems 1.9.0 is released.

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

Before I figure out how to work around the "Error - all directories must have permissions of 755" when uploading to AUR, the src package is at:

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

@stalafin, linking against openblas is now handled automatically when numpy is being built from source if openblas-lapack is installed (no change to numpy files needed, not even to site.cfg). I'd imagine it should similar for scipy.
