emacs-app: error invoking gcc driver

[Jonathan Stickel]

There is a macports ticket open for emacs/emacs-app on Sequoia:

https://trac.macports.org/ticket/71047

It is interesting that you were able to install and activate emacs-app 
+nativecomp, but later experienced warnings and errors, whereas the 
reported behavior in the ticket is failing at the activate step. In any 
case, disabling nativecomp provided a successful workaround.

Alan, thanks for the reddit link. That might be a solution for a patch 
to the port. I suggest sharing that link on the ticket.

Regards,
Jonathan
