Peter,

Until I can help you get the wiki updated. I have at least put my version
of the latest instructions to build a MythTV v32 on a RPI4 on the MythTV
Forum at
https://forum.mythtv.org/viewtopic.php?f=46&t=4799

Let me know what you think and if there is any way to take that HTML and
migrate some of that to the wiki.
