Hello again,

I think there were some typo in the patch line.
I downloaded a tar.gz patch archive from gentoo forum :
http://dev.gentoo.org/~gienah/unsupported/etc-portage-patches-x11-drivers-nvidia-drivers-340.76-for-kernel-gt-3.14.tar.gz
Now nvidia-drivers compiles fine and everything is ok.

Sorry for the noise,

Cheers,
