 The new `replaced_by` keyword doesn't always seem to work completely. In
 this case, when I asked `port` to upgrade libmp4v2, it correctly installed
 mp4v2 as its replacement, but then left libmp4v2 installed (but
 deactivated) stating faac depended on it. `port deps faac` shows it
 depends on mp4v2 not libmp4v2, though faac may have depended on libmp4v2
 at the time that I installed it.
