EAGLE DRC gives errors for clearance in a .8 TQFP

I am laying out a 64 pin TQFP with 0.8mm lead spacing. The pads are 9 mil apart. I am getting clearance errors. I have 2 questions:

How do I stop the “error” in lead spacing from being reported.

Is a spacing of 9 mil apart adequate? This is what the library for the Atmel device gives me.
