Same exact thing happened to me in my 02S. Coolant coming out of the same area when I shut the car off after getting particularly hot in stop/go traffic in the summer. I thought I was in for a big ticket maintenance bill at the dealer.

It turned out the cap on the coolant reservoir in the rear of the car was either loose or crooked. Porsche does have a new cap (don't know the part number) for like 17 bucks at the dealer which supposedly had a better/new seal to it.

Hope it is the same thing...
