Geoxito will look and email conclusion about new releases of ubuntu and which Tcl version is going to be delivered with them, and installed by default just installing simply Tcl.
I don't remember that from the meeting :P
Anyway, lenny is freeze and the default is 8.4. Aolserver package is compiled against 8.4 too, and ubuntu imports aolserver and tcl packages from debian unstable, which is using 8.4 too:

http://packages.ubuntu.com/intrepid/tcl
http://packages.ubuntu.com/intrepid/aolserver4
