upgrading python on raspbian

[Gene Heskett]

I'm not a python expert by a long ways.

I have built the linuxcnc-master, which is the development branch of 
linuxcnc, a machine control program to run most metal carving machines.
Lathes, milling machines, anything you can motorize, LinuxCNC can run.
 
This requires a preempt-rt kernel which I've managed to build and 
install, all on a pi-4b running raspbian buster, the armfh-v7l version 
of debian 10.1.

But linuxcnc is quite elderly code, some of it going back to before there
was a linux, so despite being actively developed right now for x86 type
hardware but has quite a list of missing dependencies I cannot satisfy 
from the raspbian repos.

They are:

The following packages have unmet dependencies:
 linuxcnc-uspace : Depends: python2.7-glade2 but it is not installable or
                            python-glade2 but it is not going to be installed
                   Depends: python-gtksourceview2 but it is not going to be installed
                   Depends: python-vte but it is not installable
                   Depends: python-gst0.10 but it is not installable
                   Depends: python-xlib but it is not going to be installed
                   Depends: python-gtkglext1 but it is not going to be installed
                   Depends: python-configobj but it is not going to be installed
                   Recommends: hostmot2-firmware-all but it is not installable

Can anyone supply a list of python3 packages that will cover the 
functions contained in the above list?, and I will attempt to edit the 
linuxcnc srcs to use the more modern code base?

Ignore the hostmot2-firmware-all package as its available, and may not 
be actually required with the interface card in actual use. It has its 
own fpga firmware already installed.

Thank you all.

Cheers, Gene Heskett
