Hardensuse and Suse 8.0

Hey there Has anybody installed hardensuse on suse 8.0? Has anybody seen problems/bugs with that? To the installation of hardensuse: When I unpacked the harden_suse-3.5.tar.gz, there was one file with ending pl. Means that this is a perl script and I have only the do "perl harden-suse-3.5.pl" ? Any other options? thanks in advance Oliver
