First of all, in view of your low message count, a warm welcome to you, from New Zealand.
You have arrived in the right place here.
I don't know about gamin or fam but would be inclined to delete gamin via Synaptic and let those other dependencies go. Then, if fam is not already installed, install it the same way. Finally, still in Synaptic, press Reload and then, when that has finished, press Mark all Upgrades > Apply > Apply. That way, any missing necessary dependencies will be picked up and installed.
