Error: Target org.macports.activate returned: Image error: /opt/local/bin/mp4art is being used by the active libmp4v2 port. Please deactivate this port first, or use ‘port -f activate mp4v2’ to force the activation.

Something like this is what always happens when I try to port selfupdate; port upgrade installed. Sigh.
