I'm setting up a double crankset with a new front chainring which is ramped and pinned. How should I orient the outer front chainring with respect to the chain drop prevention pin? Should this line up with the crank arm, opposite the crank arm, etc?

The pin should line up with the inside of the crankarm.

Yep, the purpose of the pin is to prevent the chain from becoming wedged between the ring and the crank arm. – Daniel R Hicks Aug 30 '12 at 17:41
