Just run the 4363 installer. Don't give it any options, either (my guess is that you used --extract-only, right?).
The usr directory that it creates is not meant to be copied to your /usr directory. In particular, the usr/src/nv that is there, the sources for the kernel interface, shouldn't be put in /usr/src/nv.
The other files may not be put in the right places either, I don't know for sure. But the installer will (or at least should) get it right.
