The old xfce4-wmdock-plugin, which depended on GTK+2, has been dropped due to
all GTK+2 dependencies being removed from Xfce 4.16. xfce4-wmdock-plugin-gtk3 is
moved to xfce4-wmdock-plugin:3.
To solve this, deselect xfce4-wmdock-plugin-gtk3 and install xfce4-wmdock-plugin:
emerge --deselect xfce4-wmdock-plugin-gtk3 emerge xfce4-wmdock-plugin
