Yep, Stopped it during the install, then started it back up after the
install.

Okay, this is what I get...

        So something in Subversion is fouling up SDBM. Beyond that, I wouldn't
have a clue.

BTW:
        On an unrelated topic, for some reason, if I send to
sussman@collab.net, it bounces -- saying I'm "Spamming", I fail to see
how my emails about this problem are spam. Could something also be done
about this too?
