The package needs porting to Python 3.13.
Not sure if this is relevant, but it seems that latest updates for python now blocks the installation of beets: // !!! The ebuild selected to satisfy "beets" has unmet requirements. - media-sound/beets-2.2.0-r1::gentoo USE="-doc -test" ABI_X86="(64)" PYTHON_SINGLE_TARGET="-python3_11 -python3_12" The following REQUIRED_USE flag constraints are unsatisfied: exactly-one-of ( python_single_target_python3_11 python_single_target_python3_12 ) // I could try to add the python use flag (e.g. python_single_target_python3_12), but this requires the same use flag for all dependencies. I won't try to install beets for now since I don't want to mess with python targets.
