It's not the Berkeley licence, but it's not the GPL either, although
it's similar:

     * Redistribution and use in source and binary forms, with or without
     * modification, are permitted provided that the following conditions
     * are met:
    [...]
     * 3. Redistributions in any form must be accompanied by information on
     *    how to obtain complete source code for the DB software and any
     *    accompanying software that uses the DB software.

Note in particular "and any accompanying software".  Previous versions
of BDB were under the Berkeley licence, which is still included below
the Sleepycat licence.
