Spamassassin not working after update to 2010.1

I just updated from 2010.0 to 2010.1, and have discovered that
spamassassin (spamd) isn't running on my system.  Trying to start it get
messages like this:

Starting spamd: Oct 10 03:04:27.117 [16785] warn: server socket setup
failed, retry 1: spamd: could not create INET socket on 127.0.0.1:783:
Address already in use
Oct 10 03:04:28.118 [16785] warn: server socket setup failed, retry 2:
spamd: could not create INET socket on 127.0.0.1:783: Address already in use

etc.

I've already checked and there isn't already an instance of spamd
running.  Doing a "netstat -apt|grep 783" shows that there's nothing
else that actually has that port.

So, anyone have any ideas what's actually causing this and more
importantly, how to fix it?
