On an ~x86 system, I don't have no libxcb-xlib.so shared lib. Something left from old libxcb ?
The libxcb upgrade breaks quite a few packages if you're not using --as-needed in your LDFLAGS. Please read these instructions to fix your system : http://www.mail-archive.com/gentoo-dev@lists.gentoo.org/msg35509.html Thanks
