UMFPACK is GPLed and optional (for that reason), so we cannot distribute it.
SuperLU is under a BSDish license, is not optional, and is small enough to
include that the costs of doing so are outweighed by the benefits of not forcing
most scipy users to download and build SuperLU separately. We don't all use Debian.

As a package maintainer, you are free to patch up scipy as you see fit in order
to reuse other packages in your distribution.
