It seems to me that the original issue for the 'setuid' stuff was
not completely fixed in Perl 5.8.4: it misses the stanza 'if
$force_writable' at the second chmod (this is from virgin perl-5.8.5):
-----
            chmod 0777, $root
              or carp "Can't make directory $root writeable: $!"
                if $force_writeable;
            print "rmdir $root\n" if $verbose;
            if (rmdir $root) {
                ++$count;
            }
            else {
                carp "Can't remove directory $root: $!";
                chmod($rp, ($Is_VMS ? VMS::Filespec::fileify($root) : $root))
                    or carp("and can't restore permissions to "
                            . sprintf("0%o",$rp) . "\n");
            }

This is in line with the Niko Tyni's patch:
  http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=36;filename=sid_fix_file_path;att=2;bug=286922

So perl >= 5.8 <= 5.8.8 seems to be affected too.
