C++ driver: executable with static ruby + static python

[jmarrec]

I doubt this is the end of the trouble at all, but I have a working executable that is self contained with ruby and python, and more complex bindings than originally

I create a model from the C++ side, add a ModelObject to it. Then run a ruby measure that renames that model, and creates another one. Then a python measure that renames the one created from ruby, and adds a third one.

I can move the executable on my disk, and it still works (the path to the measure.py/ measure.rb are harcoded, but that's the only thing it "loads" dynamically)
