При попытке установить Drupal 5.3 выдает следуюющую ошибку:

The following errors must be resolved before you can continue the installation process:

In your ./sites/default/settings.php file you have configured Drupal to use a server, however your PHP installation currently does not support this database type.
The Drupal installer requires write permissions to ./sites/default/settings.php during the installation process.

Может кто чего подскажет?
