Kevin, in that case, the acs-kernel package might be all you need.
You can likely just run the necessary install scripts manually from
sqlplus, without getting AOLserver and Tcl into the act at all,
although I don't remember now whether that's at all straightforward.
If you've already installed AOLserver, etc., then the easiest route is
just to do the minimal OpenACS core install, with no add on packages.
If you don't actually use many of the tables, that's ok, they'll just
sit there with zero rows taking up no space anyway.
Btw, why Oracle 8i? It is so old, and 10g is much nicer in
my experience.
