[Exim] DB problem on FreeBSD 5.0

Hi,

I'm having the same problem that others have reported
earlier regarding the DB files on FreeBSD with Exim 4.12
("failed to open DB file /opt/exim4/spool/db/retry:
Inappropriate file type or format").

This is on an almost fresh install of FreeBSD 5.0/x86.

I have tried to install Berkeley DB 3 and 4, but I can't
seem to get Exim to use anything but 1.8. Could someone
please tell me exactly how I tell Exim to use the newer
versions? I have read dbm.disuss.txt, but I couldn't see how
to specify which version to use.

Thanks for any help.
