In the future, please wrap these things in <pre></pre> tags and change the posting type to HTML. FAR more readable that way.
The first problem I see is:
Error: dbdrv: no such driver 'ora8'
Are you using oracle? Is it installed?
If you haven't already, check out https://openacs.org/doc/openacs-4/unix-install.html for installation guidelines. I'm guessing you incorrectly specified which DB you're using? If so, check out conf-db, and recompile aolserver if incorrectly set. Also check that you used the nsd-postgres script, not nsd-oracle.
Of course, if you're actually using Oracle, hopefully someone else will chime in and help. It might help if you could post your version of /usr/local/aolserver/birdnotes.tcl also.
Good luck!
