determining db version

[Robert Fitzpatrick]

I am trying to move my config to another server, copied over the
partition and config files, but the server seems to be complaining of my
db version. I thought it was 4.3 and with that was what I built imapd.
Can someone tell me how to determine what version my existing Berkeley
db files are in and how to confirm the db version used to build imapd?
Or how can I handle this?
