Comment 12 for bug 883324

Just copying the executable wasn't enough on my systems. I recommend also copying the 1.4.0 file rkhunter.conf to /etc. After that, create a new file /etc/rkhunter.conf.local and populate it with ALL the different (uncommented) lines from your old 1.3.8 rkhunter.conf.

In my opinion, whoever does the repackaging of 1.4.0 for ubuntu distribution will have to make some adjustments to the installation script to follow this new (and improved) scheme for managing local changes to the configuration file.
