In OS X 10.6.x you will have iChat 5.x.x and the version numbers of each that you have posted are a match at that level.
However it will not be iChat 5 that is used in OS X 10.5.8 (that will iChat 4.0.8 which is sometimes displayed as ver 4.0.9 depending on the order of a Security Update).
Have you set up Parental Controls on one of these computers ?
If you have then iChat can have all Buddy List Blocked (you then allow Buddies to be seen in the Buddy lists)
