Although the new ebuild leaves /usr/lib64/libxcb-xlib.so.0.0.0 in place, the symlinks are not. Thus, programs that link to libxcb-xlib.so.0 are dead anyway (which was all of mine). I've had quite the pleasant struggle getting my system to a shape where I could launch KDE and it's possible that re-adding these symlinks may have not been what did it, making this report invalid. However, running revdep-rebuild --library libxcb-xlib.so.0.0.0 found no broken packages at all, I suspect because they were linked to "libxcb-xlib.so.0". I can see that this file was superfluous and serving no purpose, but this transition is proving to be very trying. Running revdep-rebuild (without any arguments) returned most of my system, even gcc! (it was just the gcc java compiler's awt libraries). It would appear that the solution is to make sure the symlinks are correctly installed and modify the "revdep-rebuild " text in the postinst to whatever will correctly locate the old library.

In case anybody else finds this bug because their system becomes broken by this problem, I resolved it like this: cd /usr/lib64 ln -s libxcb-xlib.so.0.0.0 libxcb-xlib.so.0 ln -s libxcb-xlib.so.0.0.0 libxcb-xlib.so
That is a workaround but definitely not a fix. If that library should be there, then the install of libxcb should put it there.
Please read the post install messages. It points you to [1]. And please stop symlinking libraries around. This is going to break the other day. [1] http://www.gentoo.org/proj/en/desktop/x/x11/libxcb-1.4-upgrade-guide.xml

Had you actually READ what I wrote, you would have also been able to see that what einfo outputs in postinst is different than what's on the guide. Either correct the that instructions you to run "revdep-rebuild --library libxcb-xlib.so.0.0.0" from the postinst or remove it completely, don't just be lazy and close the bug invalid because you don't want to deal with it.
Please remove the symlinks and run : env-update Portage is supposed to do that, and that should fix your issues while you finish your upgrades. Thanks PS, please try to stay polite in your comments, bugzilla is a work tool, not a soapbox to vent your anger.
(In reply to comment #9) > PS, please try to stay polite in your comments, bugzilla is a work tool, not a > soapbox to vent your anger. Sorry, I hate being blown off when I take the time & effort to report problems. Perhaps there was a better way to solve my immediate problem than create the symlinks, but it got me going far enough to fix remaining issues. In response to Sebastian's "Please read the post install messages." comment, I'm saying that the post install is part of the problem. * Old versions of installed libraries were detected on your system. * In order to avoid breaking packages that depend on these old libs, * the libraries are not being removed. You need to run revdep-rebuild * in order to remove these old dependencies. If you do not have this * helper program, simply emerge the 'gentoolkit' package. * * # revdep-rebuild --library libxcb-xlib.so.0.0.0 * * Once you've finished running revdep-rebuild, it should be safe to * delete the old libraries. Here is a copy & paste for the lazy: * # rm '//usr/lib64/libxcb-xlib.so.0.0.0' * libxcb-xlib.so is no longer shipped by libxcb but was kept on your system * * While your system will still work, emerging new packages or updates * will likely fail. You can fix broken libtool .la files by running : * * /usr/portage/x11-libs/libxcb/files/xcb-rebuilder.sh * * To completely get rid of libxcb-xlib.so references, please read : * http://www.gentoo.org/proj/en/desktop/x/x11/libxcb-1.4-upgrade-guide.xml After looking at the sources, I can see that this message (the one containing the offending instructions) isn't text directly generated from postinst. Generated by "x-modular_pkg_postinst" maybe? In my particular case, I followed the instructions in postinst and when I read the guide, I did not notice the subtle difference in the instructions, and ignored what appeared to be a duplicate of the postinst message: postinst says: revdep-rebuild --library libxcb-xlib.so.0.0.0 guide says (-L is the same as --library): revdep-rebuild -L libxcb-xlib.so.0 I'm not the only one who has been thrown off by this. Sorry I don't have a patch or other recommended solution to offer, but the problem needs to be fixed, otherwise, you end up sending numerous people off on a "wild goose chase" running a command that takes 10s of minutes, only to do nothing.
Did you even try what I just suggested to you? And if you sync again, you'll see that I removed the confusing double messages a few days ago. So please, sync again, try what I suggested and then reopen this bug if you have issues, but let's concentrate on the issues. Thanks

(In reply to comment #11) > Did you even try what I just suggested to you? > > And if you sync again, you'll see that I removed the confusing double messages > a few days ago. Sorry for the late reply on this. My problem was solved when I ran the revdep-rebuild command from the guide, "revdep-rebuild --library libxcb-xlib.so.0" so it would appear that the root cause of this bug was indeed the post_inst message giving incorrect instructions. Again, I originally ignored the revdep-rebuild command from the guide because it appeared to be a duplicate of what I already ran from the post_inst message, but of course, was different. So since this is not an invalid problem and you have fixed it, why don't you close it as "RESOLVED FIXED"? Thanks
Meh, old bug. Thanks anyway :) Closing fixed
