I can see now - it makes sense to include SuperLU, so that at least
one solver is working out of the box for every scipy user. Generally
though, my philosophy is not to distribute other programs in projects,
but rather it is the job of the linux distribution (whichever you use)
to do so.

OK, thanks for clarification.
