Compilation issue on macOS 12.3

[mustafaquraish]

This likely seems to be an issue on my end, but I haven't been able to figure this out, so hopefully someone on here has an idea. Here's the error I get when I clone the repo and run pip install --verbose ..

For context, I'm in a 2019 16" macbook pro (Intel i7, so shouldn't be any ARM weirdness with m1 chips).

$ pip install --verbose .

Here's what I have tried to do so far:

• Make sure pip and python are up to date, and in sync.
• Run pip install --upgrade wheel setuptools

However, neither of these have seemed to help. I'm unsure if this is helpful or not, but I did clone the pybind11 repo itself and run the tests, they seem to run successfully.
