Comment (by bestlem):

 Looking again I note that thius does build under BigSur - but under
 Homebrew
 As per recent issue upsteam https://github.com/garrigue/lablgtk/issues/120
 The maintainer says it does work and he uses macports (but as a guess not
 for the ocaml bits)

 Thus it is still maintained

 I have a newer log after selfupdate (attached) - still I think the same
 error

 It looks like macports ocamlc.opt is injecting -isysroot into the C
 compilation

 The upstream build instructions use ocaml's dune to build. I tried
 macports' ocaml-dune but that failed with the same error. SO I think the
 issue is with our ocaml stack.

 As I don't know ocaml I can't look further
