Tim helpfully reminds me that you're using the dbapi to Berkeley, which
doesn't create an environment.  I've never actually run Berkeley without
an environment (i.e. a directory that contains all the db files) and
IIRC we couldn't find much information on running Berkeley in that type
of configuration.
