Try installing the standalone update in Safe Mode...

Safe Boot from the HD, (holding Shift key down at startup).

Any luck yet?
Im having the same, my system will not even boot from safe boot, as it was a fresh install
I ended up having to erase my HD and start from scratch. Apple support tried everything to avoid that but it was the only solution in the end.
Thanks for the report my friend. :)
