I spoke to soon. This error happened again after python23-pth-2.3nb3 was
installed but before pyxml.

I am now using latest bmake too (as installed from pkgsrc today).

I tried your suggested fix above. It did not work for me. At first, I
don't think that is used anyways, because PKGNAME_REQD does not appear to
be defined (according to show-var target). But I commented out that line
and it continued fine.

I don't know where the problem is. I will send-pr this if I can reproduce
on another system.

My workaround is to undef PYTHON_VERSION_REQD (or define it) in (My PYTHON_VERSION_REQD=23pth in my Makefile is not used.)
