Emvideo field doesn't *actually* implement hook_requirements

/**
 *  Implementation of hook_requirements().
 */
function hook_requirements($phase) {
  $requirements = array();
  // Ensure translations don't break at install time
  $t = get_t();

  if ($phase == 'install') {
    if (drupal_get_installed_schema_version('content') < 6000) {
      drupal_set_message($t("Some updates are still pending. Please return to !update and run the remaining updates.", array('!update' => l($t(), 'update.php', array('query' => 'op=selection')))), 'warning');
      $requirements['cck'] = array(
        'title' => $t('CCK'),
        'description' => $t('Updates for content.module need to be run first.<br/>Please re-run the update script.'),
        'severity' => REQUIREMENT_ERROR,
      );
    }
  }

  return $requirements;
}

Need I say more?
