xfce4-panel-4.6.4 has variable called "localedir" in it's pkg-config file, but 4.7.2 doesn't. it's required by xfce4-xfapplet-plugin, please see: http://foo-projects.org/pipermail/xfce4-dev/2007-May/023068.html http://foo-projects.org/pipermail/xfce4-dev/2007-May/023069.html ./configure output of xfce4-xfapplet-plugin: checking for libxfce4panel-1.0 >= 4.3.20... 4.7.2 [ .. ] checking for libxfce4panel-1.0 localedir... not found *** You need xfce4-panel 4.3 (SVN) >= r19874 to *** *** compile xfce4-xfapplet-plugin. *** the offending code in configure.ac: dnl check special variable localedir for libxfce4panel AC_MSG_CHECKING([for libxfce4panel-1.0 localedir]) LIBXFCE4PANEL_LOCALE_DIR=`$PKG_CONFIG --variable=localedir libxfce4panel-1.0` if test "none$LIBXFCE4PANEL_LOCALE_DIR" = "none"; then AC_MSG_RESULT([not found]) echo '*** You need xfce4-panel 4.3 (SVN) >= r19874 to ***' echo '*** compile xfce4-xfapplet-plugin. ***' exit 1 fi AC_MSG_RESULT([$LIBXFCE4PANEL_LOCALE_DIR]) AC_SUBST([LIBXFCE4PANEL_LOCALE_DIR]) i'm not sure if this is a bug in xfce4-panel or xfce4-xfapplet-plugin, if the removal was intentional, or not...
panel-plugin.c in xfapplet is using following: xfce_textdomain ("xfce4-panel", LIBXFCE4PANEL_LOCALE_DIR, "UTF-8"); so propably it needs to be readded to xfce4-panel
