I think I've figured that out, but there's actually another wrinkle.
'make install' is installing the eln files in

    
nextstep/Emacs.app/Contents/MacOS/lib/emacs/28.0.50/native-lisp/28.0.50-24e3df15

but the emacs executable is looking for them in

    nextstep/Emacs.app/Contents/MacOS/../native-lisp/28.0.50-24e3df15/

And just to add the confusion I feel they should *actually* be
installed in

    nextstep/Emacs.app/Contents/Resources/native-lisp

or similar.
