  Nope, it is the same as for Ubuntu. libc++ headers are in `/usr/include/c++/v1/` and come with FreeBSD itself, and Clang is installed into `/usr/local/llvm60` prefix. So builtins are in `/usr/local/llvm60/lib/clang/6.0.0/include` and there are no libc++ headers in there.

It looks like the latter comes from a local installation, probably the one used to compile KDevelop. (It's the last argument.) But I'm not sure how this is related to the missing `/usr/include`.
  
  
  Hum. I just noticed that `/usr/lib/clang/6.0.0/include` dir. FreeBSD ships with base compiler, which is also Clang and that dir is builtin dir for the base clang. While it shouldn't be there, I doubt it is the cause of the problem.

  Still working on this.
