12.10 - DKMS error when installing amd drivers

I need to install AMD drivers in my Ubuntu 12.10.

I followed What is the correct way to install proprietary ATI Catalyst Video Drivers (fglrx) directly from AMD? (and I installed all dependencies from 12.04 guide)

Here is my logs:

Check if system has the tools required for installation.
Uninstalling any previously installed drivers.
