[Numpy-discussion] numarray patch: use Apple's vecLib on Mac OS X

[Andrew Straw]

Hi all,

Here's a patch for numarray (against current CVS) to build using  
Apple's vecLib (optimized BLAS library) on Mac OS X.  This was inspired  
by/stolen from Bob Ippolito's recent Numeric patch (  
http://mail.python.org/pipermail/pythonmac-sig/2004-November/ 
012077.html ). To build with vecLib, set the environment variable  
USE_LAPACK=1.  I can test any modifications needed to incorporate this  
into the main release.  After building with this patch (both with and  
without vecLib) I ran Lib/testall.py with no problems -- are there more  
tests I should do?

Cheers!
Andrew
