--------------------+------------------------------
 I've installed clang-14 to macOS 10.7 as `port install clang-14`. An
 attempt to compile trivial program:
 {{{
 #include <iostream>
 using namespace std;
 int main() {
    cout << "Hello, World!" << endl;
    return 0;
 }
 }}}
 fails as:

 thus, an attempt to simple run `clang++-mp-14` fails:
