It can't find boot/math/constants.hpp

Hi @jdtuck thank you for opening this issue! It looks like a case of a missing header file in the source dist that we submitted to PyPI. I will correct this and patch it on PyPI soon.

But the fact that your MacOS system is building from source instead of one of the pre-built wheels for MacOS is also curious to me.

What version of MacOS are you running (OS version and intel vs silicon)? And what version of Python are you installing stochtree with?

[jdtuck]

MacOS 26.4.1 Silicon, Python 3.14.4, in a conda environment

Ah, that would explain it. We'll add 3.14 support to the cibuildwheel matrix in the forthcoming release.
