I ran rkhunter and got this warning: lsof: WARNING: compiled for FreeBSD release 5.4-RELEASE; this is 5.4-RELEASE-p6. I'm guessing what it means is that when I upgraded the base system that lsof wasn't rebuilt along with it? Is that going to cause a problem at all? How do I rebuild it so that I don't get that warning every time I run rkhunter?
