Simon's calling this vecLib is a bit misleading. 'vecLib' was a
vectorized library for PPC Macs, and
To use veclib you need
--with-blas="-framework Accelerate"
My full building script on OS X is currently
../${SRCDIR}/configure SHELL='/bin/bash' \
--prefix=/usr/local/R/${R_VERSION} --disable-R-framework\
CC="/usr/local/clang8/bin/clang" \
CXX="/usr/local/clang8/bin/clang++" \
In my understanding, almost all of the speed up comes from using an
optimized BLAS. Optimizing LAPACK tend to have negligible impact on
performance. At least that is my impression, although I won't say I'm an
expert.

Hi Simon,
Thanks for the info. I was totally unaware of ABI, vecLib, etc and that
Apple has blas, lapack, etc. But after reading up on this and re-reading
your email, I'm beginning to understand more about this.
So, I would like to first checkout vecLib. From what you say, would I have
to do
