OK, I've found what's happening. Nothing beats having the source code.
It turns out it's nothing to do with updating ports, a bent INDEX-8 file
or anything like that. Here's what was happening:
/etc/periodic/weekly/400.status-pkg calls pkg_version. For each
installed port, pkg_version cd's to the port directory and forks a
make -V PKGNAME
to get the latest version of the package, and if that comes back blank
you get the "Failed to get PKGNAME from
/usr/ports/<foo>/<bar>/Makefile!" error message that was my problem.
Immediately before I updated ports I'd been trying to understand the
details of the make {build,install}{world,kernel} process as I'm trying
to do something vaguely similar to nanobsd. As a result of this playing
about I had DESTDIR set in my environment. For some reason having
DESTDIR set makes some, but not all, port makefiles fail to set PKGNAME.
(E.g. on my box, with the ports updated as of 13:35 UTC yesterday,
net/GeoIP doesn't set it, archivers/xz does.)
unsetenv DESTDIR cleared the problem. Why a set DESTDIR has this effect,
and why it's only on some ports, is something I haven't tracked down
yet, and it's going to be a low priority task. If anyone does know why,
I'd be interested in the explanation.
