funciton GDALAllRegister not found, django 1.8a release on windows

[mattxbart]

Hi all,
I had a working 1.7.4 (using geodjango) on windows 7 install, no issues. I'm using osgeo4w to manage all the gdal/gis libraries. When I install the django 1.8a release or off git master, I get the following traceback:

$ ./manage.py shell

I've installed all 32bit libs, looks like something in the new raster functionality? How can I get this working?

Thanks,
