My 2010 XC did the same thing at first, and others have reported theirs is the same.
I really didn't worry about it, just torqued the bolts to spec, wiped it off and watched it.
I bought the bike in April, and by June it had stopped leaking. Now it's tight and clean.
The gasket has a gel bead around it and I think it just needs to get good and hot to seal properly.
Every day is a good day to ride. Some days are just better than others.
