Ruby from the 3.0 distribution is broken - don't know which version is
included in antlrworks. But Martin is currently working on it (commit
message from the perforce repository):

 - fixed calculator example 
 - hidden channel is identified by :hidden symbol

So you may grab it from <http://fisheye2.cenqua.com/browse/antlr/>, build it
and (somehow) tell antlrworks to use that version. Or wait for the next
release.
