Lack of libclang

[siscia]

Thanks for this wonderful repo.

Only one thing that I noticed is the lack of clang that actually breaks all my builds.

Libclang is used by bindgen.

Now it is late, but I guess it is a simple as adding,
apt-get install llvm-3.9-dev libclang-3.9-dev clang-3.9
to the install script.

Before to go ahead and provide a PR I would like to know the maintainers opinion.

Cheers,

Yes, please. :D
