PHP Fatal error: Cannot redeclare content_access_action_grant_node_permissions()

Upon enabling the Content Access module and its Content Access Rules Integrations submodule I get the following error. (Note error does not occur when only enabling the Content Access module.)

PHP Fatal error: Cannot redeclare content_access_action_grant_node_permissions() (previously declared in /home1/useraccount/public_html/beta/sites/all/modules/content_access/content_access.rules.inc:92) in /home1/useraccount/public_html/beta/sites/all/modules/content_access/content_access_rules/content_access_rules.rules.inc on line 272

I manually disabled the both Content Access and its submodule and the site's working again. I then re-enabled only the Content Access module as a work-around. Still, the Content Access Rules Integrations submodule is unusable.

Per https://drupal.org/node/72099 two functions with the same name will cause this problem.

content_access.rules.inc has this code:

function content_access_action_grant_node_permissions($node, $settings) {
  if (_content_access_rules_check_setting($node)) {
    $ca_settings = array();
    foreach (_content_access_get_operations() as $op) {
      $settings += array($op => array());
      $ca_settings[$op] = array_keys(array_flip(content_access_per_node_setting($op, $node)) + array_flip($settings[$op]));
    }
    content_access_save_per_node_settings($node, $ca_settings);
    // A following node_save() updates the grants for us.
    return array('node' => $node);
  }
}

content_access_rules.rules.inc has this code:

function content_access_action_grant_node_permissions($node, $permissions) {
  if (!empty($node->nid) && _content_access_rules_check_setting($node)) {
    // Transform the value to the content-access format.
    $settings = content_access_rules_transform_rules_value($permissions);
    $ca_settings = array();
    foreach (_content_access_get_operations() as $op => $label) {
      // Merge in the array of role-ids for each operation.
      $settings += array($op => array());
      $ca_settings[$op] = array_keys(array_flip(content_access_per_node_setting($op, $node)) + array_flip($settings[$op]));
    }
    content_access_save_per_node_settings($node, $ca_settings);
    content_access_action_aquire_grants($node);
  }
}

Is this the problem or am I missing something? (I'm relatively new to php coding.)

Thanks,
