…ibility Python 3.13 (shipped with Debian Trixie / Pi OS Trixie) removed distutils from the stdlib. The Python bindings build via setup.py, which imports distutils.core — causing both make clean and make build-python to fail with ModuleNotFoundError: No module named 'distutils'. Adding python3-setuptools to the prerequisites apt-get install line provides the distutils compatibility shim and restores the Python bindings build. The C demo and all C examples are unaffected; this only impacts the Python bindings. Tested on Pi Zero 2WH + Adafruit RGB Matrix Bonnet (3211), Convenience mode, Debian Trixie 13.4 / Pi OS (64-bit) April 2026 release.
