 0:21.17 Please specify the 'LLVM_CONFIG' environment variable
 0:21.17 (recommended), pass the '--with-libclang-path' and '--with-clang-path'
 0:21.17 options to configure, or put 'llvm-config' in your PATH.  Altering your
 0:21.17 PATH may expose 'clang' as well, potentially altering your compiler,
 0:21.17 which may not be what you intended.
