Error when starting nginx

[haunted2]

Hello, i followed the tutorial here https://github.com/perusio/drupal-with-nginx , but at the point to restart nginx, i got this error in logs:

2015/03/01 09:55:53 [emerg] 10763#0: unknown directive "aio" in /etc/nginx/apps/drupal/drupal.conf:149

That means that your nginx wasn't compiled with aio support. Unless you are doing streaming of media files it can be safely removed
