Accidently Deleted x11, Help?

[AyoLily]

So I permanently deleted x11 (The application inside of the utilities) from my Macbook Pro and I don't know how to recover it. I don't wanna pay to restore it back. So does anyone have any suggestions of what I should do?

Well, if you permanently deleted it, you can get it back from your install CD via Pacifist, which will get specific packages out to install to your Mac
