Ryan as far as I know there is no boot script needed. It was fairly straightforward when I installed it on Ubuntu Breezy Badger.
That message looks like a daemontools message, and they aren't usually very helpful in general. You could try removing the "supervise" directory in openacs/etc/daemontools, and rebooting. I'm not sure if you had previously installed daemontools and that the supervise directories are incompatible between daemontools and runit.
