Is there a way to automatically edit port Makefile and plist after updates

[Reko Turja]

There is one port that has completely unneeded things in both Makefile 
and plist. Is there a way to Automatically change those afterwards - I 
guess usual method of patching isn't applicable?

Of course doing a portsnap fetch update and sedding the unneeded stuff 
out from a shellscript each night instead of just portsnap is always 
an option if there's nothing more refined available.
