so anyone who wants to know if stumbling on this thread, gtk is the environment for smart-gui and can be installed through yast and your cds or dvd. the wiki at labix.org states all the dependencies needed by smart except for this, though that was a while back when I installed smart, perhaps it does now. once gtk is installed, as well as the others, smart should have no problem installing. the wiki even mentions that using smart through command line isn't the optimal option.
