No problem!  I'm glad its (somewhat) usable.

Yes, Alistair pointed out this problem earlier this week.  Theres a few
issues that this touches upon -- the most serious being a bug that we've
encountered where re-running genmake (1 or 2) results in malformed
(circular) links every *other* time.  I'll try to check in some fixes
soon.

Alistair also complained about that yesterday.  I'm working on a fix for
that right now.

Again, you're right.

CNH, AA, JMC, and I agree that the way packages are currently built is
messy and far from optimal in terms of compilation effort.  The only
thing good about the way that its now handled is that its "safe".

So if the goal is:

 "adding a package to a previous build should not mean a complete 
  recompile of everything"

then how do we get there?  Chris explained a fix to me yesterday and,
again, I'll try to get it checked in soon.
