Hi,I made a careless, strong 'aptitude dist-upgrade' and half my system disappeared. Since then, I cannot install wxvlc (or gxine, see bug #318019) without having to uninstall libglu1-xorg, x-window-system-core and xbase-clients. Which dooms me to watch movies with the libcaca ;-)
I think it's the same dependency problem with the xlibmesa-glu. But there is no reportbug concerning this package.
