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 !
It temporarily broke my system too, but nothing dramatic:
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
resulted in a build failure (a package complained about missing symbols
in libxcb-xlib.so during the link step). According to the upgrade
guide, that was not supposed to happen. The fix was easy though; I just
ran revdep-rebuild at this point (not many packages needed a rebuild, I
guess having "--as-needed" in my LDFLAGS saved the day) and then I
repeated the command, finally deleted /usr/lib/libxcb-xlib.so* and
everything was fine.
One other slight breakage was revdep-rebuild wanting to rebuilt the same
package over and over again. If revdep-rebuild wants to repeatedly
rebuild a package, you have to unmerge that package first and then
re-run revdep-rebuild; only then will you see the final packages that
need to be rebuild (in my case, kde-base/systemsettings).
Of course, rebooting the machine before finishing all of this is not a
good idea.
