[Beso]

it's been about 10 days that i have the following compilation error in
xorg-server git version:

i'm on gentoo x86_64 unstable branch with the live ebuilds from x11
overlay. the kernel is 2.6.26 with gentoo patches and drm working
well.
i've upgraded the protos, libs and now i'm trying to upgrade
xorg-server, but still getting this failure on xorg-server. is there
someone who experiences the same issue or it's more like a gentoo
problem?

i also have the following error on libxcb:

make -j8 -s
