It seems you have clang 3.1~+rc1-1 and:

I also get this result with this configuration but upgrading
libclang-common-dev to 3.1~+rc1-1 seems to fix the problem.

I guess clang's dependency on libclang-common-dev could be more strict
so that clang and libclang-common-dev would be upgraded together.

Hope that helps,
