FWIW, I think macOS Emacs users can do without a package manager.  I
built Emacs and its dependencies manually on a Mac using only the
built-in Command Line Developer Tools.  I guess I should write the
instructions down in nextstep/INSTALL.

Recommending a package manager that breaks so often to our macOS users
is doing them a disservice.  I think there have already been several bug
reports during the past year related to Homebrew changing their
libgccjit package.
