qt5-qtlocation @5.15.15_0 Failed to build on macOS 15

[jcm36]

QGIS no longer builds via macports on MacOs 15 due to llvm-14 no longer being supported/maintained.

I have tried to build QGIS3 excluding the plugin_support312 using the following command: port install qgis3 -plugin_support312

This failed with the following error: Failed to build qt5-qtlocation: command execution failed
