Wings, missing dependency on 13.1

I've heard that Wings is a 3D modeller that's easy to use; I've never done any of that but thought I'd check it out. Installation attempt yields "nothing provides libSDL_sound" and offers to abort or break the program by ignoring the requirement. Funny thing is, I found and installed libSDL_Sound-1_0-1. Does anyone know what Wings is looking for?

Thanks,
