As you know I am new to Gentoo, and I am experimenting some problems which I may call “Newbie problems” one of them was this.

When I tried to update my Gentoo Operating System, and I run.

sudo emerge --sync

And then,

sudo emerge --update --newuse --deep world

I got this problem:

 Failed to emerge media-sound/alsa-driver-1.0.18a, Log file:

>>>  '/var/tmp/portage/media-sound/alsa-driver-1.0.18a/temp/build.log'

 * Messages for package media-sound/alsa-driver-1.0.18a:

 *  The die message:

Well, the problem just go away as soon as I recompile the new kernel sources that was downloaded in a prior intend to update the system.

I went from kernel 2.6.25-gentoo-r8 to 2.6.27-gentoo-r8 and then I was able to run

sudo emerge alsa-driver

Actually I do not know the why was this, but I think it was because the newer version of alsa-driver needed the newer version of kernel to properly work.

Hope this may help somebody.
