Try doing a locate instead
you should have
/usr/local/psa/var/modules/watchdog/lib/rkhunter
/usr/local/psa/etc/modules/watchdog/rkhunter.conf
Then you can install the new one and sym link locations and config files. That may work for your needs, but either way you can install the one from ART packages and then just run manually or put into cron job
Code:
updatedb
locate rkhunter
you should have
/usr/local/psa/var/modules/watchdog/lib/rkhunter
/usr/local/psa/etc/modules/watchdog/rkhunter.conf
