Python in PTXdist is a bit tricky. We don't want to compile Python itself just to run a few Python scripts at build-time. That's what "host-system-python3" is for. It does not build anything, it just checks if Python3 and required packages are installed. "host-python3" is used when building Python packages for the target. In this case, it looks like the wrong Python is used. Which ptxdist version are you using?
