Can I use Macports for Gimp maintenance?

[Lukas Oberhuber]

Given we support all the way back to 10.12, I'm worried about trying to get
that version of macos up and running reliably with the build tools.
Homebrew also doesn't go back that far, which is one of the main reasons
I'm looking at macports. It seems I've now got the bare bones working
(thought it's hard to tell if the right SDK was linked). In
any case, thanks for your help!
