The portupgrade port will install portsclean which can clean up working 
directories and remove distfiles that aren't referenced by any installed 
port.

There's another port* command I can't recall the name of that will list 
ports that are not required by any other port which you can then decide if 
you want to remove.  Might be an option to pkg_info, I really don't 
remember.
