No, engineering is easy. If it is unbroken it should be at least as 
strong as concrete. The epoxy in anchors will work. If the rock is not 
perfectly level you can do a thin concrete pad on top of the rock to 
make a flat spot to bolt to. Drill the anchors through the concrete 
leveling pad and into the rock.

I love anchoring to rock. It's free and not going anywhere!
