This has most likely happened because you have an old version of clang installed with LLVM_TARGETS="BPF" but your latest installed version does not have it. This is what the check is supposed to guard against. Unfortunately there's no way to enforce this purely through Portage dependencies. :( I could iterate through numbered SLOTs with has_version but it wouldn't be pretty so I'd rather not. Unfortunately there's no ebuild helper to iterate through installed versions like portageq can.
I'm seeing this issue with no clang/llvm installed and with the correct LLVM_TARGETS defined. In other words, portage should be pulling in the correct packages, but they are not installed now, and I get this error. That can't be what is intended. Should I have to to install clang first manually before installing this package? That seems counterintuitive to the idea of a package manager.

We therefore need to check again in pkg_setup().

Thanks!
