Well i don't really feel that chkrootkit and rootkithunter are needed to be installed. Cos if your system's compromised then there's a good chance of those being corrupted. So, you'd rather have these on some live CD and if you feel your OS has rootkits then boot up with the live CD and run any of them. So, no chances of compromise. But, I am not sure how well does it catch up with rootkits.
