Emacs v XEmacs in ports

Mark,

Thanks for your reply.

Am I naive to propose that, in the case of something system-supplied  
like Emacs, the dependency be omitted?

For Mozart it turns out I can override the default (emacs) by setting  
an environment variable (OZEMACS=xemacs). Everyone can do this, so  
IMHO the dependency on MacPorts emacs should be dropped.
