This is because a RUN_DEPENDS like

emacs>=23.3:${PORTSDIR}....

means 'check for a package called "emacs" and make sure its version is
at least 23.3'

whereas a RUN_DEPENDS like

emacs:${PORTSDIR}...

means 'check for the presence of an executable named emacs on $PATH'
which works because either the emacs or emacs-nox11 packages will
provide an emacs binary, but obviously doesn't allow for checking the
version numbers.

So

emacs>=23.3:${PORTSDIR}/editors/emacs-nox11

is non-sensical, and should probably be rewritten as

emacs-nox11>=23.3:${PORTSDIR}/editors/emacs-nox11
