This was my question, and your little sketch of history here makes it
clear.
Now everything is just about ready with the blas/lapack/atlas suite on
i386, ppc, sparc, alpha, mips(el) and (probably) s390, but the
addition of the integrity checks to the build have revealed apparently
insuperable compiler issues on hppa,arm,ia64, and m68k. It looks as
if I'll have to request the ftp-master to pull the old binary packages
for these :-(.
Thanks again!
