This is not a serious blocking issue, however I'd still like to have it resolved: $ pkg-config --list-all ... Package qt-mt was not found in the pkg-config search path. Perhaps you should add the directory containing `qt-mt.pc' to the PKG_CONFIG_PATH environment variable Package 'qt-mt', required by 'avahi-qt3', not found I searched and realized that qt-mt.pc definitely doesn't exist on my computer, and AFAIK it shouldn't.
