Sorry I wasn't clear, I use the information on the old package to delete
the old distfiles, after first comparing to the list of distfiles used
by other ports to make sure that it isn't in use elsewhere (such as QT).

In portmaster un-installing the port is a different option from
upgrading, and has a component of deleting the current distfiles if the
user chooses it.
