How are you building? Did you build the Python bindings? I need to get 
up to speed on building with VS, but I'm pretty sure you need to build 
GDAL the usual way, then build the python extensions with:

python setup.py build

You should install with:

python setup.py install

make sure you're using the same python for building and installing.

This looks like you haven't built the extension.

It shouldn't be, as long as you make sure to build against the same one 
you install it in.

Yes, it is!

I'd expect an option in the nmake.opt file, but I don't see it listed on 
this Wiki page:

http://trac.osgeo.org/gdal/wiki/BuildingOnWindows

Let us know if you figure it out!
