Without that link, -lXvMCNVIDIA defaults to link a static .a that creates not small problems with plugins for example in xine-lib. The reason ldconfig doesn't do that link automatically is that its soname is libXvMCNVIDIA_dynamic.so, thus libXvMCNVIDIA.so is not in the list of links to do. Thanks, Diego
Fixed bug in new x11-drivers/nvidia-drivers-1.0.8762.ebuild Give it a try. :-)
