Comment (by jrh@…):

 Here's an alternate patch (v2) which does not create the +app variant.
 Instead, it first looks for the Emacs.app binary, and if that fails then
 it automatically falls back to the emacs binary.  This is how the gnuplot
 port does it, and I think it's a more elegant solution.  If I have
 installed '''emacs-app''' via MacPorts, then other Emacs-using ports
 should transparently accept it as a suitable Emacs binary without forcing
 me to manually set a variant or redundantly install '''emacs'''.
