I've tried everything and it seems to install but doesn't work when I open the lens cover. I typed this "python /usr/lib/hildon-desktop/lfocuswi.py" in xterminal and I get: Traceback (most recent call last): File "/usr/lib/hildon-desktop/lfocuswi.py", line 1, in <module> import gtk, pygtk, os,sys,time,math,hildon,hildondesktop.dbus,gobject ImportError: No module named hildon
