chkrootkit output help

I just ran chkrootkit on a machine that was just installed with freeBSD 5.0. It is connected to the net behind a NAT router and it has only been up for about 2 days. I updated all of the ports and the src before installing. It does not seem like much of a risk.....

Just wondering how I find out how to specifically find if these are false results are not. Is there a good site explaining what I should look for when trying to find chfn, chsh, date, ls, ps chkrootkits?

Thanks!
