it is using the macOS version /usr/bin/emacs. Are you using the emacs variant? Because in that case the configure should use the right binary. What the command /usr/bin/emacs --version returns? If the port is without any variants, we should disable the emacs inclusion but this should be the default. Also, I notice that your are on PPC.

If it is supposed to use emacs in any case, even without a variant, then it is likely that my system binary does not work (I never used it or even checked). Not an issue then, can be closed as wontfix. (I can take care of the system emacs binary, and proper emacs builds fine at the moment.)

by default emacs is not selected. The check is done ​here and should be enough to detect incompatible versions and other issues. What the command /usr/bin/emacs --version returns in your installation?

That’s some Apple weirdness: to “install” emacs for ppc one needs to run /usr/libexec/dumpemacs, otherwise the binary won’t run. Anyway, not MacPorts bug.

Interestingly, building with emacs from MacPorts fails: ​https://github.com/djcb/mu/issues/2873 (system one works).
