media_build failures on 3.0.6 Gentoo

[Fredrik Lingvall <fredrik.lingvall@gmail.com>]

Hi,

I get this build failure:

lin-tv src # git clone git://linuxtv.org/media_build.git
lin-tv src # cd media_build/
lin-tv media_build # ./build
Checking if the needed tools are present
Needed package dependencies are met.

* ./backports/<kernel> directory.                          *
* It will also update this tree to be sure that all compat *
* bits are there, to avoid compilation failures            *
