Hi, as I have just bitten by it, have a look at http://bugs.gentoo.org/show_bug.cgi?id=285004
before upgrading to x11-libs/libxcb-1.4 (1.4.-r1) since this breaks any X11-application (including your browser to look at the URL above) Such an update should be DOUBLY MASKED !!! And the messages coming with libxcb just don't help. revdep-rebuild doesn't help either. And one cannot remerge the broken packages either, since there configure bails out. Oh dear, Gentoo !
