BTW, my apache package built with X11_TYPE=modular does depend on an
expat package, so at least part of this is working.

Yes, the setting of X11_TYPE *shouldn't* be meaningful for apache, but
I got the impression from the PR that it *is* meaningful.
Having now looked more carefully at the pkgsrc makefiles, I suspect that
the problem was that the apache binary package was built on a system
where IS_BUILTIN.expat was true, but was installed on a system without
expat. That won't work, and fixing it may require changes in the way
binary packages deal with prerequisites that may or may not be "built
in" to the host system.

I think that adding expat to base should have a beter reason than
"there's something wrong in the way pkgsrc builds apache, and this is
the quickest workaround we can think of".
