Hi,
I had some problems with nvidia-drives and kernel 3.8.0:
https://forums.gentoo.org/viewtopic-t-951692-highlight-.html
so I had to downgrade to 3.7.8.
It looks like everything is fine, but I had some such messages 'Could not find a Makefile in the kernel source directory' after last emerge -uDN world.

* Unable to check for the following kernel config options due

Yes, I was running depclean to add one of the driver (in manually install) after moving into 3.8.0.
But because there is a problem with 3.8.0 and nvidia-drivers:
https://forums.gentoo.org/viewtopic-t-951692-highlight-.html
I had to go back to 3.7.8.
Now some more packages says Unable to calculate Linux Kernel version for build...
So what should I do? I cannot go for 3.8.0 as this bug with nvidia. |

Xywa ... its not simply a matter of installing the sources, you have to prepare, and or/build, them. It sounds as you have installed sys-kernel/gentoo-sources-3.7.8 but haven't run 'menuconfig', 'oldconfig', 'make' (or what-have-you) and for this reason there is no 'Makefile'. So, assuming you have CONFIG_IKCONFIG_PROC=y you will have the .config for the currently booted kernel in /proc and can do the following:
| Code: | # zcat /proc/config.gz > /usr/src/linux/.config
# cd /usr/src/linux && make oldconfig |
If you don't have IKCONFIG_PROC enabled but have a known working config from some previous build then you can do the following:
| Code: | # cp /path/to/gentoo-sources/.config /usr/src/linux/.config
# cd /usr/src/linux && make oldconfig |
This should create the missing Makefile, and your ready to either 'make && make modules_install' or 'emerge nvidia-drivers'.

Many thanks for all sugestions.
Anyway, I did emerge gentoo-sources again (with masked >3.7. and it did the job
