How can I prevent rkhunter from always giving me the same warnings?

I get these warnings every single day from Rootkit Hunter:

---------------------- Start Rootkit Hunter Scan ----------------------
Warning: Package manager verification has failed:
         File: /usr/sbin/tcpd
         The file permissions have changed
Warning: Package manager verification has failed:
         File: /usr/bin/less
         The symbolic link target has changed
Warning: Package manager verification has failed:
         File: /usr/bin/telnet
         The file permissions have changed

----------------------- End Rootkit Hunter Scan -----------------------

And yes :-) I have run rkhunter --propupd before and after this problem started. No change, still get these warnings every day. Why and how can I stop them?
