Emacs port does not upgrade

[Watson Ladd]

When I update emacs, I get a binary named emacs-23.4 instead of an
updated emacs. Is there a good reason for this behavior?
I can think of several reasons why it is not good, and the port
message displays no information about this, nor does the build
message.
What gives?
Sincerely,
Watson Ladd
