Oops. Upgrading via source is always tricky. There were a lot of changes
between 1.4 and -current, many to do with the build process.

I thought we were supposed to be getting new packages... (wondering if
the person who was going to do it will speak up..)
If not, I think I still have Bill Sommerfeld's script around. It reaches
into gnu/dist and builds a compiler chain.
