Which knobs do I use to control BDB use in MySQL-server port?

Mysql 5.0's configure script doesn't seem to have a --without-bdb flag,
so it always gets built.

It does have a --with-berkeley-db=DIR flag, so you could add that to
CONFIGURE_ARGS to force an external bdb to be used instead of the one
bundled with mysql.  Note that the bdb engine has been removed from
mysql 5.1, so you should think about moving any bdb tables you might
already have to innodb.  Development on the bdb engine pretty much
stopped once innodb was available.
