i think we all collectively kind of answered the question. i don't think the op necessarily wanted to run the actual aol instant messenger program. rather, i think he wanted to chat with his buddies without resorting to running a chat client on windows. again, adium and ichat both do the trick. i don't think aim 4.7 is a good option since it's grossly outdated, and it isn't intel-native. universal binary ftw!
