After a recent emerge my NVIDIA driver stopped working due to ABI conflict with the xorg-server-1.8.4. So I have been trying to install a new version of NVIDIA driver using the NVIDIA intaller NVIDIA-Linux-x86_64-367.44.run. Then I got into trouble when the installer couldn't find the kernel.h:

ERROR: The kernel header file '/lib/modules/3.17.7-gentoo/source/include/linux/kernel.h' does not exist. The most likely
reason for this is that the kernel source path '/lib/modules/3.17.7-gentoo/source' is incorrect. Please make sure you
have installed the kernel source files for your kernel and that they are properly configured; on Red Hat Linux systems,
for example, be sure you have the 'kernel-source' or 'kernel-devel' RPM installed. If you know the correct kernel
source files are installed, you may specify the kernel source path with the '--kernel-source-path' command line option.

Any suggestions are appreciated.

OTOH your kernel is outdated.

At certain point in the past, the x11 version of nvidia driver didn't seem to work. Anyway, I couldn't get it emerged either

does the /usr/src/linux symbolic link point to an active Linux kernel tree?
It seems the link points to a uninstalled version (there remain only .o, not the Makefile).

Well in /usr/src/linux the kernel.h was missing. Following the suggestion from the first response, I installed the latest kernel. Then I was able to install the latest nvidia proprietary driver. Finally X is working again, even though some of the problems reported earlier still remain (but probably don't matter for now).

Thanks for all the responses.
