I hit the same issue today on ARM (Raspberry Pi 4B+). My best guess is that there has been a change in INDI that breaks PyINDI. For example, I also noticed that `pyindi-client` `master` does not build against `indi` `master` right now. I had to roll back `indi` to the most recent tag to make it build. I will try rolling back INDI further and let you know if I succeed.
