I am happy. I just wanted to thanks Igor, Esteban, Eliot, David, INRIA, and anyone involved with the progress in VM side.

Today, in less than 1 hour, I could modify the method lookup to add support for proxies, compiled the stack vm and run it. Of course, it was not working, so I needed to debug. But I like debugging with XCode, not gdb directly. So, what I did?� cmake -G Xcode�� (Esteban suggestion).
and I was debugging with XCode.

Summary: I could do all that in 1 hour. Thanks a lot.
