You are missing some libraries. Try searching for "IEEE" in synaptic and 
install the ones you are missing. Dont forget to install the -dev 
packages too. I have it working on ubuntu and its proven to be pretty 
stable as long as you do not try to tune a channel with disabled 
firewire output. That seems to lock things up pretty good.
