Cyrus imap db3 db4

[Mike Lohmann]

Hi,

I am using Berkeley DB - 4.0.14 (as it was recommended for Cyrus-imapd - 
2.0.12)

The compilation and installation of cyrus-sasl and berkeley works without 
problems, but whenever I try to compile (make all CFLAGS=-O) cyrus-imapd, 
I've got the following problem:

cannot find libdb3.so. 

I know, that this problems is because of a not installed 3.x version of 
berkeley db. When I install this db3 -version (libdb3 - debian package) the 
compilation works fine. 

My question is:

Is it possible to use the db4 libs instead of the db3 ones for the configure 
parameters --with-duplicate-db, --with-mboxlist-db?

When I use the db3 libs for the configure parameters: Will I run in trouble 
when I am using the cyrus server?

All examples and howtos (HowTo install cyrus imap) don't tell anything about 
that problem.

Can someone help please?

Thanks.

Mike
