The message means that some part of the system - libraries probably -
have been changed and hence the prelinking of commands (passwd,
chkconfig etc) now requires to be redone. Hence you get the warning
message, and an advisory to run the 'prelink' command.

Your system will, at some time, automatically prelink the relevant
commands/libraries, but if you want to avoid the rkhunter warnings until
then, then run the suggested prelink commands.

Run the shown prelink comands and then run:

  rkhunter --enable properties

The warnings should have gone.
