I don't think that's the problem. I'd guess that none of the tcl procs are initialized correctly.
You can test this out by making a simple test page and using the commands from there.
Or you can put an ns_log notice "XXX initializing" at the top of the file, restarting aolserver, and seeing if you notice that in your error log. I bet it won't show up.
It might be something earlier that's preventing it from starting up. It's hard to tell.
