Yes, configure does not detect that NDBM in FreeBSD & OpenBSD is
emulated by Berkeley DB 1.85.
As I have no real .dbm bases to use, nor real NDBM library, 
I just commented out the following line in config.h
#define HAVE_NDBM_H 1
Then Zmailer uses native DB 1.85 dbopen() from libc without problems.

On the other hand, if you've installed Berkeley DB 2.x or 3.x from SleepyCat
it never finds them in default locations (bug in configure.in IMHO)
/usr/local/BerkeleyDB/{include,lib} for 2.x
/usr/local/BerkeleyDB.3/{include,lib} for 3.0.x
/usr/local/BerkeleyDB.3.1/{include,lib} for 3.1.x
(And library is always called libdb.a, no matter which version).
I don't believe you should use funny -I and -L for default locations.

I'm not familiar enough with autoconf tools to make correct changes in
configure.in .

Maybe it's still better to be able to tweak configured db libraries
and locations from SiteConfig?

You are wrong. That definition is correct (there are no .pag file
when NDBM is emulated by Berkeley DB). But in some cases it may be
sufficient to
#define dbm_pagfno(a) dbm_dirfno(a)
