Comment(by bob.spamnot@…):

 Why the delay on this upgrade?  It should be straightforward.  I've
 enclosed a Portfile which I think should work.  It eliminates all mention
 of carbon, has no emacs-app as that is in a separate port (which I see is
 already upgraded to 23.1) and updates the md5.  I don't think any
 patchfiles are needed and the --without-x is changed to
 --with-x-toolkit=no.

 Give it a try (on Leopard, as I've heard emacs won't compile on SL but
 that's a separate issue).
