I haven't changed the package to use setgid game and removed the
other-writeable, since such files should not be created under
${LOCALBASE}. Bump revision.
Remove `-p' from mkdir arguments, it is already part of ${MKDIR}.
While here substitute a couple of ${PREFIX} by `%D' in
`@exec ${MKDIR} ...' lines and add a couple of missing `%D' in such lines too!
