Hi, I think this change (specifically hdf5) is causing install to fail in the following CI run
https://github.com/yt-project/yt/actions/runs/11987726777/job/33422224913
is this expected ? how should we go about it downstream ?

@neutrinoceros , Can you add a command to remove un-wanted pkg-config before you install the packages?

brew uninstall pkg-config@0.29.2

macos runner have changed a bit, and will be fixed on next release, would takes 1~2 weeks, I guess.

• [macOS] Replace pkg-config with pkgconf in all macOS images actions/runner-images#11015
