It's more that I don't *want* to update to something newer if I
don't have to. Also it seems very un-python-like to depend on a
specific OS version like this, which leads me to believe that
something is wrong somewhere.

Actually it seems to be more a matter of my XCode being *too*
new. I was using XCode 9, which turns out to contain an SDK
for 10.13. Which shouldn't matter, except that there seems to
be a bug in autoconf that makes it think some things are there
even though they're not:

That's talking about a slightly different scenario (building
with one version and running on an older version) but I think
I'm being bitten by the same underlying issue.

I'm going to try again with XCode 8, which purportedly comes
with a 10.12 SDK, and see if that fixes it.
