Actually I use Mandrake; the reason I'm doing this is that I had weird
compilation problems that I couldn't figure out on the other machine,
and decided if this would work it was easier than beating my head into
a wall trying to get it to compile.  It SHOULD be configured almost
identically, save for hardware.
