Hello!

I've found a bug with permission system.

There's no permission "administer facetapi pretty paths" in control panel, so it seems no one but UID 1 can setup module.

This is because Drupal 7 style hook_permission() is used instead of Drupal 6 hook_perm(). Hook_permission is never called in Drupal 6.

Sorry, I can't make patches, so the working hook_perm for this module is here:

/**
 * Implements hook_perm().
 */
function facetapi_pretty_paths_perm() {
  return array('administer facetapi pretty paths');
}
