[РЕШЕНО]Не собирается nvidia-drivers-310.32

Сейчас стоят дрова nvidia-drivers-313.18, система x86, ядро 3.7.9-gentoo (единственное).
Хочу собрать последние стабильные nvidia-drivers-310.32.
При сборке пишет:

# emerge -v =x11-drivers/nvidia-drivers-310.32

If you are using a Linux 2.4 kernel, please make sure
you either have configured kernel sources matching your
kernel or the correct set of kernel headers installed
on your system.

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.

>>> Failed to emerge x11-drivers/nvidia-drivers-310.32, Log file:

Система свежеуствановленная. До этого драйвер 313.18 собрался без ошибок. Что я опять сделал неправильно? Как сделать правильно?
Нашел несколько советов, в том числе использовать emerge module-rebuild && module-rebuild populate && module-rebuild rebuild, но тому совету больше 3-х лет и версия драйверов сильно отличается. Стоит ли ставить module-rebuild или это уже не актуально?
PS: пробовал пересобрать 313.18, та же ошибка.
