Well, it should be better to use "python(filesystem) = 2.7-1" or 
something like that IMO. It turns out that for integration of JRuby, 
even if we would stay with Ruby 1.9.3, we would need to change 
filesystem layout and ruby(abi) cannot reflect it. I feel that the above 
mentioned usecase is abuse of python(abi).
