What problem is that supposed to work around?

Also everyone: Don’t actually do that, it’s bad advice. /usr/local exists to be managed by you, but /usr outside of /usr/local is to be managed by your system’s package manager (pacman/libalpm).

simdjson workaround: sudo ln -s /usr/lib/libsimdjson.so /usr/lib/libsimdjson.so.23

this package is currently waiting for the scikit-build maintainers’ help in building python-libmamba/micromamba.

in the future python-libmamba will probably be replaced with micromamba since with a few tweaks, it can provide everything provide everything this package needs.

Then the dependency chain will be python-conda-libmamba-solver->micromamba
