It seems to need the 2.5 kernel sources. But it doesn't have a dependency for it. And it seems to search it also in the 2.4.22-gentoo-r2 sources where it also won't find it.

It needs 2.6, not 2.5 sources; I've added a fatal warning to the ebuild now A dependency wouldn't work as there are many kernel trees which provide 2.6 sources, and it is up to the user to select one, not for Portage. Thanks.
