Looks like you have got in a bit of a mess here.
My Tutorial was written for Apache 2.2.x and it looks like you are using Apache 2.4, guess I forgot to mention that, but then so did you.
2.2 uses the form
Order Deny,Allow
Deny from all
Allow from 127.0.0.1 ::1
2.4 uses the form
Require local
If all else fails, you could always try reading the Apache manual on the Apache webs sit
