Sorry for the late. I only tested on ubuntu.

I can see a llvm-static package for fedora:

https://apps.fedoraproject.org/packages/llvm-static/

but for clang I can find only dynamic libraries:

https://apps.fedoraproject.org/packages/clang-libs/

I think we can make it work by changing 'libclang$(l).a'
to 'libclang$(l).so' in commit 1125e7f6cf29.

Thank you.
