Ok, I misunderstood your problem then.

I think your best bet is deleting the old tree and extracting it again 
with portsnap, this would not be very fast though.

If you use zfs you could leverage it, using snapshots and clones. You 
could snapshot the official tree, clone it, modify the cloned one(munted 
in /usr/ports) and when you upgrade destroy the clone and create a new 
clone from the updated official tree, which would be clean without local 
modifications.

subversion could help too. You could perform a "svn revert -R ." 
followed by svn up. This would be faster than "rm -r * && portsnap 
extract" (done in /usr/ports, obviously)
