Ola, I'm not sure if you're still having trouble or not... if you are,
you could try out PG 7.1.2 + AOLserver 3.3+ad13 + OpenACS 3.2.5 from my RPMs and see whether they work for you.
I've not made my RH 7.1 aolserver-3.3+ad13 RPMs public yet but they exist and work for me, though admittedly I start nsd using a Red Hat init script and not from inittab. If you want to be a victim^H^H^H^H^H^Htester for these RPMs under RH 7.1, let me know. It's about time I made this stuff available anyway 😊
