x11-drivers/nvidia-drivers-260.19.29 was built with the following: USE="acpi gtk (multilib) -custom-cflags"
I had the same symptoms when emerging this driver; the problem was that I did clean the linux sources after the kernel build. The nvidia build system compiles a little testprogram to determin the kernel version (2.4 or 2.6). This testprogramm did not compile, because a file generated during the kernel build -- namely generated/asm-offsets.h -- was removed by the make clean. I just started to compile the kernel again until the file was generated. I then interrupted the kernel build and emerged the nvidia drivers without a problem. You can play with the build system in /var/tmp/portage/x11-drivers/nvidia-drivers-260.19.29/work/kernel after the emerge failed to test if you have the same problem.
Thats the problem. When building a kernel with umask 0027 the emerge process cannot read the appropriate file (permission denied; emerge build will be done with portage user --> no rights to read files generated by root:root with mod 750) Currently i have to switch the umask before building the kernel
Nothing we can fix in the NVIDIA drivers. Non-root users can't access your kernel sources, Portage runs things not as root by default. Either config Portage to run as root or fix the perms on your kernel source tree.
