So I just accidentally messed up my mac :angry:, so I won't be able to fix those `yaml-cpp` bugs very soon and also we would have to wait for them to be released. So I will make a ticket to track yaml-cpp 0.5 support and make one of the tasks be to switch this entry back to yaml-cpp 0.5 when we are ready for it.

To be clear my recommendation is to use yaml-cpp 0.3 for now.
