 Replying to [comment:4 kencu]:
 > Second -- so, why aren't you getting the binary for `gmp` from the
 buildbot? Why is your system trying to build it? Have you set it up that
 way on purpose?

 Because the gmp port deliberately disables binary fetching. See #41614.

 > Third, now why are you running as root? That could well mess up your
 path, and other things. I never run as root, and there's precious little I
 can't do with `sudo` when I need it.

 I agree with that.

 > I don't think this has to do with 10.12.6,

 Why not? If Xcode requires that version of macOS, and the user doesn't
 have it, that seems a highly likely cause for the failure.
