It's pretty much the standard nowadays to only have one rear fog lamp located on the drivers side. The reason given is that it's easier for following drivers to see the change in your cars rear lights when you step on the brake if you have only the one. Whilst that does make some sense you can't help feeling slightly short changed the first time you see it.
This is part of the original German TUV requirements. The TUV is like the Department of Transportation (DOT) in the USA.
Cars registered in Germany are required to have at least one rear fog lamp. If only one lamp is fitted it must be mounted low (so it is lower than any fog, in order to be seen) and must be on the outboard (driver's) side. Porsches imported to the USA retain this German feature, which is actually a good thing.
So your car is fine and the fact that it only has one lamp is completely normal.
Personally, I like the little "secret" pull switch for this lamp.
In thinking about this, I wonder if Porsche switches the rear fog lamp side on right-hand drive cars? Silly question I suppose, but does anyone know?

Yes they do & so do other manufacturers as I stated in my original reply. When only one fog lamp is fitted on a car it's supposed to be on the drivers side. You'll actually find that with some manufactures all the sockets/terminals are present on both sides but they just aren't wired on one side.
