Thanks for the feedback! Maybe I'd install an OpenIndiana VM in my PC!

Yes. In this last batch of updates, I needed to break compatibility. So, 
to avoid a lot of trouble to users in the future, I added a new 
#pluginApiVersion primitive. Now, not only the existence of the plugin 
is checked, but also that it provides a compatible API with the 
Smalltalk code.
