 Tried to install llvm-15 on High Sierra (10.13.6), Xcode version 10.1.
 Failed with error:
 {{{

 have unmet dependencies (likely due to a dependency cycle): clang-13
 clang-11 clang-9.0 ld64 ld64-latest libtapi clang-15 llvm-15 llvm-11
 llvm-13

 This was nearly the first port I attempted to install after a fresh
 install of MacPorts. List of currently installed ports attached.
