v0.15~preview.124.16+217 build fails on macos

[mudrz]

hey, got redirected here from: janestreet/bonsai#12 (comment)

I tried to compile core.v0.15~preview.124.16+217 with ocaml-base-compiler.4.11.1 on macos, but it fails:

[ERROR] The compilation of core failed at "/.opam/opam-init/hooks/sandbox.sh build dune build -p
        core -j 7".
-> installed async_js.v0.15~preview.124.16+217
-> installed incr_dom.v0.15~preview.124.16+217

I believe this is fixed by janestreet/jst-config@e5fdac6. I'm closing this issue for now, but please feel free to reopen if that commit didn't resolve the issue for you.
