installworld and delete-old fighting a constant battle

hi there,

while installing world with DESTDIR!=/ and running delete-old afterwards, i
noticed the following entries. if i'm not mistaken delete-old should not need
to delete anything, because DESTDIR was completely empty before running
installworld:

>>> Removing old files (only deletes safe to delete libs)
remove /usr/obj/TESTDIR/usr/share/man/man3/archive_entry_hardlink_w.3.gz? y
remove /usr/obj/TESTDIR/usr/share/man/man3/archive_entry_symlink_w.3.gz? y
>>> Old files removed
>>> Removing old directories
/usr/obj/TESTDIR/usr/include/fs/fifofs
/usr/obj/TESTDIR/usr/include/lwres
/usr/obj/TESTDIR/usr/share/doc/bind9/arm
/usr/obj/TESTDIR/usr/share/doc/bind9/misc
/usr/obj/TESTDIR/usr/share/doc/bind9
>>> Old directories removed

my src.conf contains the following entries:
