Gentoo compile error

[nemessiss]

i initially posted on hhvm repo but they closed my thread (take a look here https://github.com/facebook/hhvm/issues/2458#issuecomment-40556148)

I want to rebuild hhvm under gentoo to preserve the libs but i get an error:

OCaml is not binary compatible from version to version, so you
need to rebuild all packages depending on it, that are actually
installed on your system. To do so, you can run:
