To reclaim disk space if you don't plan to revert to an older version, you can fully uninstall old versions by specifying their complete version and variant line. For example, if "port installed" shows you have qt4-mac @4.6.0_0+universal installed, and you don't plan to go back to that version, you could uninstall it by typing "sudo port uninstall qt4-mac @4.6.0_0+universal". If you already know at upgrade time that you don't want MacPorts to retain the older version(s), and you want MacPorts to uninstall the old version(s) when installing the new one, use the "-u" flag to port upgrade, e.g. "sudo port -u upgrade qt4-mac".

And if you know that you don't want any of those 'inactive' ports any more, you can do 'sudo port uninstall inactive' to remove them all with one command.
