Conrad--

I guess I'm thinking of a case where you didn't want to rely on a  
particular gem being present on a target machine -- say for an app you  
were distributing. Naturally, the GEM_HOME built into MacRuby is just  
fine on *my* machine. But, if I give the app to someone else who may  
not have a particular gem installed, boom!
