I would have thought that it should "just work", but since it doesn't, I'm seeking some guidance as to how I should update that port appropriately.

Ctypes uses dlopen behind the scenes, and if you look at dlopen's man
page, it only searches a small set of fallback paths when the full path
to the library is not supplied, most of which are controlled by
environment variables. So I would say that py-libnacl should be passing
the full path to libnacl to ctypes.cdll.LoadLibrary.
