Comment(by jmdeldin@…):

 I've got it working! Bob Halley graciously sent me his upstream patch, so
 here's what you need to do to fix the build error and title bar problem:

 1. Update your Portfile with this patch:

 2. Add this patch to dports/aqua/emacs-app/files:

 3. port install emacs-app

 This patch should hit upstream sometime, at which point the Portfile edits
 and title-bar patch can be removed.
