Apache и mod_dbd Получение «DBD: mod_dbd несовместимо с APR в get_driver»

Я пытаюсь реализовать базовую аутентификацию с сервером Apache и плагином, прокси-часть работает отлично, но когда я пытаюсь выполнить предварительный запрос, который, как предполагается, запускает mod_authn_dbd и его зависимость, я получаю эту ошибку:

[Sat Sep 03 17:42:38 2011] [error] (OS 126)The specified module could not be found.  : DBD: failed to initialise
[Sat Sep 03 17:42:38 2011] [error] [client 192.168.16.2] Failed to acquire database connection to look up user 'admin'

вот моя конфигурация:

что я делаю не так? mysql работает (phpMyadmin отлично работает), а прокси-сервер apache работает отлично.
