Looks like pybind11 was not updated. How was this even supposed to work?

Replying to barracuda156:

Looks like pybind11 was not updated. How was this even supposed to work?

You answered your own question in the upstream ticket: there is both a py-pybind11 and pybind11 port (the lattes one uses Python 3.11). Most likely you had the {{{pybind11}} port installed and that caused the confusion of headers.

I see two options:

1. remove the pybind11 port and migrate dependents to the pyXY-pybind11 (sub)port
2. do the same thing as for py-meson, meson and have the pybind11 port depend on the subport for MacPorts' default Python versions (i.e., currently py312-pybind11) and create the necessary symlinks

I would be in favor of options 1 given the very few dependents and am willing to look into doing this, unless there are clear objections and/or considerations I am missing.
