cd /usr/ports/x11/kde3
for dep in `make -V RUN_DEPENDS`; do 
	origin=${dep##*:};
	portname=`make -C ${origin} -V PORTNAME`;
	pkg_delete -Xf "^${portname}-[0-9\.,_]+\$";
done
cd /usr/ports/ports-mgmt/pkg_cutleaves
make install
pkg_cutleaves -xg

Delete all leaves you are sure you don't need anymore, till no leaves are
