Well, but port auctex also declares its dependency on "port:emacs".  
Only the port emacs can satisfy that dependency. If other ports would  
also be suitable, the dependency in auctex could be rewritten like  
"path:${prefix}/bin/emacs:emacs" so that any port that installs e.g.  
the emacs binary in the MacPorts prefix would satisfy the dependency.
