Apple does’t include the command line utilities in Xcode by default any more.  It’s a new “feature” they call “Install on demand.”  The site that Apple sends you to for XQuatz is a valid and curated site.  

Also, discussions elsewhere imply that we may lose X11 hooks in a future OS X as it has no bearing on the native Apple GUI realm any more.
