I've been looking at this problem for quite a while, and there
are many, many issues with automatically updating packages with
make update (though it's still wonderfully useful in the one-off
case).  After suggestions from many people on the list, I've got
a functional script which I use in weekly.local to rebuild all
out-of-date packages (once per week, obviously).  In short, it
does

	linkpkgsrc -i
        pkgdepgraph -R
	{parse output of pkdepgraph into pkg_comp/default.conf}
        pkg_comp auto

Then all I have to do is issue a pkg_add -u -u for any packages
which I wish to update (which I suppose you could also automate,
but that scares me too much).  I've got it working quite smoothly
now, and if you'd like I'd be happy to paste the entire script
somewhere.

Cheers,
Chris
