[Exim] Encrypted DB error?

I upgraded to exim 4.34 and now I get this error in mail.main.log:

2004-05-25 21:03:17 1BSpdM-0006Kl-Kr Berkeley DB error: Encrypted
database: no encryption flag specified
2004-05-25 21:03:17 1BSpdM-0006Kl-Kr Berkeley DB error:
/var/spool/exim/db/retry: unexpected file type or format

I used the same compile settings as I did with my previous version
(4.30). Can someone offer an explanation?
