Mmmmm... One important "detail". It is an out-of-build tree (I got it
to work), so prebuilt clang 3.4 from Ubuntu.

Eeeeh. Misunderstanding.
Nope, they cannot be pulled later from the typelib registry as that
would require the user to basically tell orogen all the files that
should be pulled (replicating the set of recursive includes). If you
think about it, really not fun when you start hitting Eigen or boost.
