Mac OS X 10.2 comes with /System/Library/Frameworks/vecLib.framework,
which contains Altivec optimized versions of LAPACK, BLAS (and of
libraries for Digital Signal Processing and BigNums, and a vector
version of the scalar libm). All this is either 8, 16, or 32 bit signed  
unsigned integers, or single precision IEEE floating point.

Browse it:   <developer.apple.com/hardware/ve>

Code it:      /System/Library/Frameworks/vecLib.framework/

Include it:  #include   <vecLib/vecLib.h>

Do it:         cc -faltivec -framework vecLib file.c

Although the use of single precision FP may be a problem for
building all of R, this framework could obviously be used to build
some wickedly fast DSP and linear algebra packages.
