planet shader in Unify wiki available in indie unity3d 3.1?

I tried planet shader from unify wiki. but on my free unity3d (version 3.1), it looks like a normal textured sphere. Planet shader doesn't work on free unity3d?

Unfortunately, the 2.x planet shader is broken in Unity 3.x. There's another question here in Unity Answers on the same topic.
