Hmmm...do you mean I need to drop the database and reinstall? Restarting the server with the current CVS checkout completely hoses the site -- all I get now is an error in the browser: "The document contained no data." from any url.
Here is the error I presume is the clue:
debug: RP (9.866 ms): rp_filter: setting up request: GET / [16/Sep/2002:14:26:44][26713.5126][-conn2-] Error: tclop: invalid return code from filter proc 'can't read "node(instance_name)": no such element in array': must be filter_ok, filter_return, or filter_break
