We do not plan to support multiple MRI versions. So there is no need for 
that.

However, this might or might not come into play for Rubinius. But if 
that will be needed, the gems should go into 
/usr/lib[64]/gems/rubinius/{1.8,1.9,2.0} probably. In that case the line 
[1] will need some additional tweaks. But the important is that the rest 
of gems will stay untouched.
