Interesting bug setting SUBLEVEL in /usr/src/linux to 6 make the drivers stop build. When using gentoo-sources-3.7.6 they won't build (see build.log) but when editing the SUBLEVEL to <6 it works. >>> Emerging (1 of 1) x11-drivers/nvidia-drivers-313.18 * NVIDIA-Linux-x86_64-313.18.run SHA256 SHA512 WHIRLPOOL size ;-) ...

If you are using a Linux 2.6 kernel, please make sure you have configured kernel sources matching your kernel installed on your system. If you specified a separate output directory using either the "KBUILD_OUTPUT" or the "O" KBUILD parameter, make sure to specify this directory with the SYSOUT environment variable or with the equivalent nvidia-installer command line option. Depending on where and how the kernel sources (or the kernel headers) were installed, you may need to specify their location with the SYSSRC environment variable or the equivalent nvidia-installer command line option. *** Unable to determine the target kernel version. *** make: *** [select_makefile] Error 1 * ERROR: x11-drivers/nvidia-drivers-313.18 failed (compile phase): * emake failed * * If you need support, post the output of `emerge --info '=x11-drivers/nvidia-drivers-313.18'`, * the complete build log and the output of `emerge -pqv '=x11-drivers/nvidia-drivers-313.18'`. * The complete build log is located at '/var/log/portage/build/x11-drivers/nvidia-drivers-313.18:20130207-091622.log'. * For convenience, a symlink to the build log is located at '/var/tmp/portage/x11-drivers/nvidia-drivers-313.18/temp/build.log'. * The ebuild environment file is located at '/var/tmp/portage/x11-drivers/nvidia-drivers-313.18/temp/environment'. * Working directory: '/var/tmp/portage/x11-drivers/nvidia-drivers-313.18/work/kernel' * S: '/var/tmp/portage/x11-drivers/nvidia-drivers-313.18/work/' >>> Failed to emerge x11-drivers/nvidia-drivers-313.18, Log file: >>> Running pre-merge checks for x11-drivers/nvidia-drivers-313.18 * Determining the location of the kernel source code * Found kernel source directory: * /usr/src/linux * Found sources for kernel version: * 3.7.5-gentoo * Checking for suitable kernel configuration options...
