With the exception of the '--prefix' and the '--enable-linux-lfs'
switches, the other switches are not necessary. If you put the ATLAS
BLAS libraries in a standard location (i.e. '/usr/local/lib') the
configure script will find it automatically.
I'm not sure there's a set of 'configure' options that is 'optimal' for
data mining. I'm not even sure what that means.
