dev driver install with linux kernel 3.0 fails

Not able to install the ‘devdriver_4.0_linux_64_270.41.19’ package on a gentoo system with kernel version 3.0.0; previous and current versions of the standard driver (‘NVIDIA-Linux-x86_64-280.13’) install without a hitch.

Installation syntax attempted…

sh devdriver_4.0_linux_64_270.41.19.run --kernel-output-path /lib/modules/3.0.0-gentoo/build --kernel-install-path /lib/modules/3.0.0-gentoo/kernel/drivers/video --kernel-source-path /lib/modules/3.0.0-gentoo/source -e

resulting error log…

       their location with the SYSSRC environment variable or

       the equivalent nvidia-installer command line option.

Just for fun I’ve tried setting the SYSOUT and SYSSRC env vars to no avail.

Has anyone enjoyed installing the dev driver onto a linux kernel 3.0 platform successfully?

Have you solved this issue?

I am using the x11-drivers/nvidia-drivers-275.09.07 and sys-kernel/gentoo-sources-3.0.6 which runs fine on my Gentoo. Also a gentoo ebuild for the 270.41.19 driver is available, so why not using on of them instead of the package you mentioned?
Best Regards
