`

Start by reproducing `pyoxidizer run` or `cargo build` and inspect the `jemalloc-sys` build-script output and its generated `config.log`. Trace the compiler invocation shown there, including the configured `x86_64-apple-darwin13.4.0-clang`, and compare it with the project’s supported build setup. Done means the reported macOS build completes without the jemalloc compiler failure.
