I'm not sure about with MacPorts, but with Homebrew it should just be
a case of installing libgccjit and configuring as normal.

If it's an Arm mac then I think it requires gcc 11.

I don't know why the Mac community tends towards maintaining huge
scripts and/or lists of configure flags for building Emacs, because in
my experience they're not required, but it does seem to be the norm.

FWIW, I don't know what the original bug report is really about. I'm
guessing it's to do with making an app bundle that can be copied to
other machines or something? That's always a problem.
