Have you tried using the semi-automatic v2 -> v3 conversion 
utility?

To answer your specific question, ANTLR v3 uses '=' instead of ':' 
for labels now, so swap that over and it should fix that.  But 
there are other problems there too -- the |! syntax isn't 
recognised AFAIK (what does that even do?), and the #s seem wrong 
as well.
