Uninstall non-active packages

[Bart Masschelein]

Hi all,

Is there a way to get a list of the non-active packages, so one could  
do sth like sudo port uninstall <list>, or sudo port clean <list>? I  
never use the -u option (read: I only recently discovered it, and will  
start using it from now one ;-)), hence I have a lot of non-active  
packages laying around.

Or in short: how can I get rid of non-active packages, for which new  
versions are already installed?
