The domain should be http://localhost and the path should be /~myusername/bbpress/ but that shouldn’t stop the database connection.

Do you know if you have PHP’s mysqli extension loaded (as opposed to the normal mysql)? If you do, try copying bb-includes/db.php to bb-includes/db-mysqli.php to overwrite that later file (it seems to be out of date).

Please let me knw if that helps or not.
