ChkRootKit looks good but when I tried to install it on my Mac Pro The installer notified me that it could not be installed because my system version was 10.4.9.

I cannot let say this. Not after 20 years of security concern.
You seem to be oriented, dear!

I'm not sure you understand that you read.
The doc say that risk coming from ‘monitor’ tools that can be oriented (by changes) to not reflect real state of system.
The FIRST GOAL of chkrootkit is to detect ‘monitors’ which not reflect reality.

No! Definitively no!
When you detect change on binary by signatures (md5, sha, …) you just establish a change in the file, but you don’t detect the signature of ‘rootkit’. You’re just able to say that files have been changed.
ChkRootKit alerts you about the ‘SIGNATURES’ of malwares not only the changes, but REALLY THE SIGNS OF MALWARE CODES in your system executables.

According to the documentation this program uses ps, netstat, uname and a bunch of other command to do its work. The only problem here is that a lot of rootkits replace these with hacked versions which do not show the programs they've installed. So unless this program includes its own "known-good" commands (it doesn't, as far as I can tell) this won't detect a reasonably sophisticated attack.
There's only one way to reliably detect these modifications and that's by using cryptographic signatures on the key system files to make sure that they have not been changed. The program for this is tripwire, which has been around for a long time. It's not really easy to use, but it will let you know that your system has been modified. (http://sourceforge.net/projects/tripwire/)
So just be aware that a clever hack will be completely undetectable to this program.
