Did you get this fixed? I'm having the same issue!
When I install the Rubber gem, I only have access to the config command. I.e. I can't call Vulcanize. See my post on Stack Overflow for a print screen: http://stackoverflow.com/questions/14522051/rails-rubber-gem-no-such-sub-command-vulcanize/14536914#14536914
Does anybody know how to fix this? It sounds like it could fix @kmamit's problem above too.
