Re-forwarding to krb5-bugs since this is a bug and I inadvertently sent to
the wrong list initially (krbdev).
Kerberos Release: 1.9.1 (but I can also confirm the bug is present in 1.8.2
and possibly other releases).

When I did a Google search for this, it appears there was a conversation
between Ken Raeburn & Greg Hudson on 2011-01-12 regarding this very topic,
but it appears it was not fixed in the sources since, but the specifics were
not covered. The issue is -lkrb5_db2 references a module which is located
in -lkadm5srv_mit. If you use shared libraries, the library order is not
important as there is lazy dependency resolution. However, if you use
static libraries, each object/library's undeclared references must be
present in one of the subsequent libraries in the link list (and in this
case, the function was present in an earlier library but not previously
pulled in because it wasn't previously required to satisfy prior
dependencies). In general, it is safe to repeat -l<library> references
(shared or static), so the fix is simply to list -lkadm5srv_mit again.
Anyway, here is a patch which addresses the issue:
