ports need a uniq identifier, do you have any suggestion?

Does pkgng handle MOVED during upgrades? If so, ${ORIGIN}_${SUBPACKAGE}
will work fine, if not -- then it should; relying on unique name not to
change is fragile.

For example when audio/polypaudio was renamed to audio/pulseaudio, it
would be unreasonable to keep it's unique name as "polyaudio".
