Oil pump gasket is far more likely than the pan gasket. There's no 
pressurized oil at the pan gasket interface, and given that it only 
leaks when the oil system is under pressure, I'd  say you're looking 
for a leak at the oil pump.

I think your only recourse at this point is to take the front of the 
engine apart, and remove the oil pump. Replace the gasket, inspect for 
cracks, and use the correct sealant on the bolts when it goes back 
together.
