The early returns are not great: we have about half a dozen machines
so far that are finding python3, and reporting sane-looking Python
include paths, but not finding Python.h. They're all Linux-oid
machines, so I suppose what is going on is that they have the base
python3 package installed but not python3-dev or local equivalent.

I want to leave that patch in place long enough so we can get a
fairly full survey of which machines are OK and which are not,
but I suppose I'll have to revert it tomorrow or so. We did
promise the owners a month to adjust their configurations.
