There is no oil pan gasket on your car. Your pan is sealed with a sealing compound, and yes, it is a bit of work to get to the pan (raising the vehicle, disconnecting the front diff, clutch or torque converter housing, etc). As USMC advises, you might want to clean around the pan thoroughly as oil (and all liquids) can travel, especially when your car is moving, so often we see oil at a distance from where it’s actually leaking from.
I suppose the first basic question would be, how often do you change your oil, and how much do you have to add between oil changes???
