Updated to libpng-1.4.8 the other day, and have been having some trouble. I can't seem to get the vlc (1.1.10) interface working properly... opening vlc from the KDE menu doesn't work at all, nor does right-clicking on a video and trying to open with vlc. I can play videos with vlc from the command line (e.g., 'vlc video.avi'), but I don't get any menubar and right-click on the video to open up the usual menu doesn't do anything. I tried running from the command line with 'vlc -v' and got the following message: VLC media player 1.1.10 The Luggage (revision exported) [0x1ddb150] main libvlc warning: cannot load module `/usr/lib64/vlc/plugins/gui/libqt4_plugin.so' (libpng.so.3: cannot open shared object file: No such file or directory) Blocked: call to unsetenv("DBUS_ACTIVATION_ADDRESS") Blocked: call to unsetenv("DBUS_ACTIVATION_BUS_TYPE") [0x1ddb150] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface. Remote control interface initialized. Type `help' for help. So it looks like this is probably related to the libpng update... but I'm not sure how to fix it. I've installed libpng-1.2.45 in addition to 1.4.8 in order to get google-talkplugin to work, but clearly libpng.so.3 is not part of this package. I've tried using equery to find which libpng version might contain this file, but got no result. I also checked the ebuild for vlc-1.1.10, and it seems to think it depends only on libpng, not a particular version.
have you re-emeged vlc, and run revdep-rebuild (from app-portage/gentoolkit) since the upgrade? also please post the output of emerge --info.
It will be a revdep-rebuild case (unless dlopen is somehow involved) -libpng-1.4.8 doesn't create libpng.so.3 symlink.
Yes, I tried both revdep-rebuild and re-emerging vlc (in that order). The only broken files that revdep-rebuild found are the following, all related to a program called mendeley (totally unrelated to vlc): * !!! /usr/local/lib64/libMendeley.so.0.9.9 not owned by any

I wouldn't call "/usr/local/lib64/libQtGui.so.4" an unrelated problem. It's more like a pretty good reason to mark the bug as INVALID.
I disagree. Note the 'local' in /usr/local/lib64/libQtGui.so.4. I know for certain that this particular file comes with mendeley (I just double-checked, diff versus the same file in a freshly extracted mendeley 0.9.9 archive produces no differences). This file may also have a problem with the libpng upgrade, but that's not what I'm reporting in this bug report. This bug report remains valid because I'm describing a problem with vlc, which isn't working right because apparently /usr/lib64/vlc/plugins/gui/libqt4_plugin.so can't be loaded (not the absence of 'local' in this library path: this is actually created when vlc is emerged). Regardless of my problems with things that I installed without using emerge, the problem with vlc is a problem with vlc in portage.
Oh, but '/usr/local' is exactly the part that makes it it invalid - portage can't fix (more exactly, revdep-rebuild) what's not managed by it. If there is more than one library with the same SONAME, only the first found is considered. By default, '/usr/local/lib' is searched before '/usr/lib', so having a broken lib there will break your system, even if the one in '/usr/lib' is OK.
OK, so I've now removed all of mendeley, re-run revdep-rebuild. No broken libraries are detected now, and vlc is still broken, with the same error message: cannot load module `/usr/lib64/vlc/plugins/gui/libqt4_plugin.so' (libQtGui.so.4: cannot open shared object file: No such file or directory)
Oops, guess that's a slightly different error message. But it's still not working... I'll try re-emerging vlc again and report back.
Thanks! Now that mendeley is gone, and vlc has been re-emerged, it all works fine.
