 emacs-app has trouble finding the gcc driver!

 ⛔ Warning (native-compiler): libgccjit.so: error: error invoking gcc

 ⛔ Warning (native-compiler):
 /Applications/MacPorts/Emacs.app/Contents/Resources/lisp/emacs-lisp/cl-
 seq.el.gz: Error Internal native compiler error: "failed to compile",
 "/Users/malfunct/.emacs.d/eln-cache/30_2-bd9d77f9/cl-seq-
