Здравствуйте, Drupalers

Возникли проблемі с установкой v6.1 на этапе инсталляции. После выбора английского языка, сразу же появился месседж:

The Drupal installer requires write permissions to ./sites/default during the installation process. If you are unsure how to grant file permissions, please consult the on-line handbook.
The directory sites/default/files does not exist. An automated attempt to create this directory failed, possibly due to a permissions problem. To proceed with the installation, either create the directory and modify its permissions manually, or ensure that the installer has the permissions to create it automatically. For more information, please see INSTALL.txt or the on-line handbook.

поискал, но описания проблемы не нашел. Помогите разобраться
