You must be very lucky to have such a fast machine.

I'm following the recipe on
http://www.gentoo.org/proj/en/desktop/x/x11/libxcb-1.4-upgrade-guide.xml

which results in

emerge -v1 -j4 x11-proto/xcb-proto x11-libs/libxcb
emerge -v1 -j4 x11-proto/xproto x11-proto/xextproto x11-libs/libX11 
x11-libs/libXext

/usr/portage/x11-libs/libxcb/files/xcb-rebuilder.sh

emerge -1 -j4 \
$(for i in x11-proto/ x11-libs/libxcb x11-libs/libX11 x11-libs/libXext \
           x11-libs/libX x11-libs/xcb-util x11-libs/cairo \
           x11-libs/pango x11-libs/gtk+ gnome-base/libgnomeui \
           x11-libs/qt-gui; do \
    qlist -IC $i; \
done) -v

revdep-rebuild -L libxcb-xlib.so.0 -- -j4 --ask --keep-going


This requires to rebuild 182 packages and proably several
hours on a modern PC (Phenom II 4 cores)

(this includes some not so tiny packages like gcc (2 slots)
several gnome and kde libraries)

(Sometimes, Gentoo is an expensive hobby)
