Content found at /comment issue

I'm using Perusio's excellent nginx configs and I'm running into an issue. It seems that a comment's title link goes to site.com/comment/comment_id As an example, I've set a test up at http://testing.caulderon.com/ If you click on the node you'll see the link for the comment goes to http://testing.caulderon.com/comment/1#comment-1 I've got a client who's content is showing up in google using the comment url and that sucks for SEO. I've edited robots.txt to block the comment path, but I want a true fix for this. Can someone help?

Thanks!
