icecat karmic 3.6.2 upgrade issue

[Mithat Konar]

I was able to successfully install Icecat 3.6-1karmic1 onto my Karmic machine 
from the PPA (deb http://ppa.launchpad.net/gnuzilla-team/ppa/ubuntu karmic 
main).

Synaptic has noticed that update 3.6.2-0karmic1 is available, however when I 
try to upgrade it, I get the following error:

icecat:
 Depends: libnotify  but it is not installable

I currently have the following libnotify packages installed:
* libnotify0.4-cil
* libnotify1
* libnotify-bin

Help?
