possibly there are better methods but i do:
pkg_info|cut -f 1 -d " " >package.list
edit package.list and remove from that list ONLY things you do need.
do pkg_delete `cat package.list`
and pkg_delete will skip everything that is needed for packages you
removed from list, and will delete everything else.
