The package needs porting to Python 3.13.
Changing PYTHON_COMPAT=( python3_{9..12} ) to PYTHON_COMPAT=( python3_{9..13} ) In the ebuild works. Can confirm the module compiles fine with python 3.13. Also ran and created a 53 meg KML file after words. Currently this is a show stopper if you have the package installed. World will not update.
