So if I understand you correctly, you're not worried about actually
supplying these apt packages, but you want equivalents so you can port
the code itself to Py3?

My recommendation would be to start with "sudo apt build-dep
linuxcnc-uspace" and see if it can get any, but otherwise, just
replace "python-" with "python3-" and see if that works. You may need
to dig up dev packages of them though.

Another option may be to just use pip to install your dependencies.
That might work out easier.
