adesklets has new dependencies when using xorg-x11 >= 7.0. To run adesklets with the option --xfce4, x11-apps/xprop and x11-apps/xwininfo are needed.
Already fixed in 0.6.1 - maybe someone might want to stabilize it. ;)
now looking after open bugs and x86 stabilization...
Open bugs fixed and package stabilized...
