portmaster has an -s switch that will remove ports no longer needed by 
any other ports, so what you can do is say uninstall port A then run 
portmaster -s and it will pick up any ports that port A required but 
nothing else does and offer to remove them. it is an alternate to 
portmanager, so you will not need both.
