Derek,
The EPB operates on a separate drum brake within the brake disc and it sounds as though it may not be functioning correctly. With the brake off, you should be able to push the car reasonably easily on level ground. If you can't then I'd get the problem looked at ASAP.
If you have Porsche Assistance you'll be able to get the car trailered in to the Porsche Centre.
