What does this error mean? Updating : gtk2 35/178 g_module_open() failed for /usr/lib64/gtk-2.0/2.10.0/loaders/libpixbufloader-png.so: /usr/local/lib/libpng12.so.0: undefined symbol: inflateReset /usr/bin/gtk-query-immodules-2.0-64: /usr/local/lib/libpng12.so.0: no version information available (required by /usr/lib64/libcairo.so.2) Do I really need gtk2 running on a server anyway?
