We're getting a lot of crashes reported by users who linked OpenLDAP and
libsasl2 with different versions of BerkeleyDB. It would probably help
if the sasldb code had the same kind of version check that we use in our
code, so that the problem can be caught immediately instead of
mysteriously arising somewhere during runtime.
