Erich,

I saw the README.SLACKWARE file but was looking for the INSTALL.txt file the
build suggested.

I've used OpenBLAS, too. After all these years I'm still not confident I
know the relationships of LAPACK, BLAS, ATLAS, and OpenBLAS. They seem to
overlap so much.

Since OpenBLAS seems to do all that octave, R, grass, and other applications
want done I'll remove LAPACK-ATLAS, and build only OpenBLAS.

Thanks for the insight!
