If you are only interested in packages which no longer have *any* files
on the filesystem, then compare the output of the following two
commands:

  pkg_info -qL package | wc -l
  pkg_info -qg package | wc -l

If the output of those two commands is the same, then there are no valid
package files left at all, and a pkg_delete -f is in order.

Moreover, if you are only interested in the existence of the files, it
would be easier to do something like:

  remove=1
  pkg_info -qL package | while read fname; do
      [ -f "$fname" ] && remove=0
  done
  if [ $remove == "1" ]; then pkg_delete package; fi

G'luck,
Peter
