[Numpy-discussion] Re: numarray 1.3.1 setup patch for mac OS X veclib

[Andrew Jaffe]

Dear All,

My apologies, but I seem to have made a mistake in the distutils patch
for OS X, which has unfortunately made it into the latest 1.3.2
release.

The bottom line is, I think, that we need an explicit include dir for
cblas.h, rather than framework.

Thus, we really need to add the following line to cfg_packages.py:
         lapack_include_dirs += 
['/System/Library/Frameworks/vecLib.framework/Headers']
in the block that deals with the veclib framework (around line 53)

This should be generic -- it's a symlink to the current version -- but I
don't know if there's a better way to auto-generate the dir name.

Sorry for not testing thoroughly enough!

Andrew
