Since upgrade to 6.x-1.1 get fatal error in status report and when trying to view module settings page in admin

After patching and re-copying I still get the same error:

Upon viewing status report:
Fatal error: Call to undefined function _advagg_build_url() in /myserver/dir/sites/all/modules/advagg/advagg.install on line 524

Upon trying to view /admin/settings/advagg
Same thing...

Seems to be there:

tail -n50 advagg.module 

  if (strpos($file, '/advagg_') !== FALSE && !empty($type)) {
    $return = array(
      'Content-Length: ' . filesize($file),
      'Cache-Control: ' . 'max-age=31556926, public',
    );
    if ($type == 'css') {
      $return[] = 'Content-Type: text/css';
    }
    if ($type == 'js') {
      $return[] = 'Content-Type: text/javascript';
    }
    return $return;
  }
}

/**
 * Helper function to build an URL for asynchronous requests.
 *
 * @param $filepath
 *   Path to a URI excluding everything to the left and including the base path.
 */
function _advagg_build_url($filepath = '') {
  global $base_path;

  // Server auth.
  $auth = '';
  if (isset($_SERVER['AUTH_TYPE']) && $_SERVER['AUTH_TYPE'] == 'Basic') {
    $auth = $_SERVER['PHP_AUTH_USER'] . ':' . $_SERVER['PHP_AUTH_PW'] .'@';
  }

  // Host.
  $ip = variable_get('advagg_server_addr', FALSE);
  if ($ip == -1) {
    $ip = $_SERVER['HTTP_HOST'];
  }
  elseif (empty($ip)) {
    $ip = empty($_SERVER['SERVER_ADDR']) ? '127.0.0.1' : $_SERVER['SERVER_ADDR'];
  }

  // Port.
  $port = '';
//   if (   isset($_SERVER['SERVER_PORT'])
//       && is_numeric($_SERVER['SERVER_PORT'])
//       && ($_SERVER['SERVER_PORT'] != 80 || $_SERVER['SERVER_PORT'] != 443)
//         ) {
//     $port = ':' . $_SERVER['SERVER_PORT'];
//   }

  return 'http://' . $auth . $ip . $port . $base_path . $filepath;
}

That did it, although I applied that over top of the previously patched file if that helps you in anyway ..... At this point I can get into admin, etc. Thanks!

Now I'm seeing a previously reported bug (I believe) in the status report:

Adv CSS/JS Agg - Async Mode Flush your caches
You need to flush your menu cache. This can be done near the bottom of the performance page. If this does not fix the issue copy this info below when opening up an issue for advagg:

I've flushed multiple times and still get the error - doubt this is related though...
