Further info:
- "python" defaults to python3 on my system
- my python3 installation is broken, and indeed launching "python" from
the command line gives me exactly the same error as lyxpak.py
So the issue seems to be that lyxpak indirectly calls "python" at some
points, this calls ends up calling python3, which fails.
I still do not understand where this misguided call to python3 comes into
the picture, though.
