your noted build error is for clang-16, not llvm-16:

The buildbot seemed to have no trouble with it.

Replying to kencu:

your noted build error is for clang-16, not llvm-16:

Indeed, it is clang-16 is broken and not llvm-16. I was confused by directory name. llvm-16 has installed fine:

10:~ svacchanda$ port -v installed llvm-16
The following ports are currently installed:
  llvm-16 @16.0.6_0+universal (active) requested_variants='+universal' platform='darwin 12' archs='i386 x86_64' date='2023-07-28T03:11:13+0800'

Now, I do not know why it is broken, but it is for sure not due to any hacks on my side: I have neither need nor any desire to do that on 10.8.5. It is a purely testing set-up and uses standard Macports tools. No building with GCC and alike.
