I'm not sure, but try running locate on your locale e.g.: $ locate en_US.UTF-8 /usr/share/X11/locale/en_US.UTF-8 /usr/share/X11/locale/en_US.UTF-8/Compose /usr/share/X11/locale/en_US.UTF-8/XI18N_OBJS /usr/share/X11/locale/en_US.UTF-8/XLC_LOCALE /usr/share/doc/libx11-dev/i18n/compose/en_US.UTF-8.html If you don't have those (or similar) locale files, you need to enable and generate that (evidently required, based on your environment) locale. Good luck,
