gtk+ error

I am trying to compile a program but it says that gtk+-devel >= 1.2.7 is needed by easytag-0.30-1 I've just installed gtk2-devel-2.2.3-27 What adjustments do I need to make in order to get it to work? (I think that gtk2 is the SUSE equivalent for gtk+ but you can correct me if I'm wrong). Thanks Eddie
