do you know if the macos pyo3 issues are still present after this commit 8766fd6 ? had you run into these issues yourself?

ideally would make this part as foolproof as possible for python users. would rather solve it in build.rs instead of having them tweak their cargo config

Yea i encountered the issue when trying to build, but not on install. Can check if it can be solved with build.rs instead
