Comment(by idoadam@…):

 Aaccording to the official Emacs.app web site (http://emacs-
 app.sourceforge.net/), emacs actually supersedes Emacs.app and the Cocoa
 version can be built by the --with-ns switch in configure (this is
 supported by the documentation in the gnustep directory in the official
 emacs23.1 tarball). Additionally, the Carbon variant is slightly different
 and is not superseded by Emacs.app either.
