greyreader failed (Error 2)

[Adam]

I recently upgraded from openbsd 4.5 to 5.3.  Everything seems to be  
working fine, but when I start spamd I get:

spamd[18275]: greyreader failed (Error 2)
in /var/log/daemon.  Greylisting seems to be working, I have new entries  
in spamdb anyways.  Do I need to create some new file that didn't exist  
for older spamd?
