Clang fails to install correctly on Gentoo Linux

I encountered the installation error below after running an update of clang on my Gentoo box. Could anyone advise, where is the correct place to raise such an issue?

Thank you in advance.

 *   LLVM_BUILD_TESTS
 *   LLVM_CMAKE_PATH

Those are pretty silly warnings and I think you can ignore them unless you have a problem running clang.

Okay, noted and thank you for the reply.
