"Nor", I think. (One of a set of confusing typos. Others include "not"
instead of "now" or "note". Note that I would ever make such silly
mistakes.)

As for the subject matter, you _can_ actually create such at thing as an
optimized, shared BLAS/Lapack, and it is probably faster than an
unoptimized, shared one (well, at least you could create them when I
played with this some years ago). It's just that people think it is a
bit silly, so they are not doing it for you, and as I recall it, you
also need to tinker a bit more than usual with the build process of the
libraries.
