I had the same error as you.
If you install apt/synaptic it should solve those dependency problems for you (synaptic is basically just a GUI for the apt program, so it will make it easier to install packages graphically). Once you install apt, you can get synaptic easily by running the following at the command line;
apt-get update && apt-get install synaptic
Then look under System Settings in the application menu and you will see it there.
