MarsSeed [1] filed a deletion request for xfce4-genmon-plugin-gtk2 [2]: The Gtk2 based Xfce4 is EOL for 5 years now. Many of its components fail to build on current Arch Linux. Some of them have already been dropped from AUR, and all others are pending deletion for the same reason. Not useful to keep this any longer. Arch extra repo carries the current upstream version of xfce4-genmon- plugin (which uses gtk3).
