  Yes, but I would like to have it fixed rather than fixing it myself :-)

Fair enough, and I already understand this, but it has been working for
me quite well with no errors.
If the require database is wrong, then that may not be handled properly.

So, if you can see what the state of work/ and /var/db/pkg/foo is next
time, and send me the details, I'll see if I can figure it out.

I did a make replace in graphics/png, after updating mk pkgtools
graphics/png and reinstalling pkg_install.  The rest of my pkgsrc is
kind of old, from 28 August.
