You left out the wash, ;) The next missing dev was a gtk thingy, but 
search only returned
one .dev. One for spice-gtk, and that pulled in around 100 more 
packages, and now its stuck
on wxPython for about 35 minutes and, way into swap, like several 
hundred megs &
growing. I even went to its keyboard and shut down chromium to give it 
more play
room. Didn't seem to help though. But it hasn't errored, and swap is 
going  down a
meg here and there. Pounding that poor, cheap sd card all to hell I 
expect. At some point,
I'll unpack a startech usb3-sata cable and try an SSD. But I'll not 
disturb this just yet.

Works well on an r-pi4b where I can build linuxcnc in half an hour from 
the git pull. I
run a 3/4 ton, 80 yo Sheldon lathe with linuxcnc just to see if I could 
do it, first on an rpi3b.
Had to build my own realtime kernel and figure out how to install it 
because I wanted to
do it on a pi, got black holed on their forum. The amazing part is that 
the tarball to install
it is only 28 megs uncompressed.

Your forgot to mention that each packager is working in his own sound 
proof booth, so
each comes up with a somewhat different way to pound that square peg 
into a 7 point hole.

It was obviously going to take hours so I took a nap and 4 hours later 
it had left out a
few things but kept on going until it hit another showstopper while 
building wxPython-4.1.
At which point it spit out 2600 some lines of backtrace.

Ending with this:

================
Now, I have the unpacked tarball of wxPython-4.2.0 sitting in 
/home/gene/src.

Where would I mv it to to substituted for the 4.1 since 4.1 isn't quite 
ready for prime time?

I changed the 1 to a 2 in requirements.txt, but that exited in a few 
seconds after it
downloaded another copy of the tarball, with another error I have see 
before while
trying to build it in /home/gene/src's/unpacked_tarball tree.

I've found it , the src tarball.gz. In /home/gene/Downloads.

Is that tarball updatable? Or should I ignore it & go back to wxPython-4.1?
Is it fixable?

Thanks Peter. Take care and stay well.
