Build fails on 2 separate Ubuntu 22.04 with pip and sudo python3 setup.py install

[iconoclasthero]

$ which python3 pip; python3 --version; pip --version
/usr/bin/python3
/bin/python3
/usr/bin/pip
/bin/pip
Python 3.10.12
pip 23.3.1 from $HOME/.local/lib/python3.10/site-packages/pip (python 3.10)

Here's the log of the machine on which it is intended to run. Also failed on a machine on which I reinstalled Ubuntu 22.04 < 12 hours ago.

gmvault-setup.py.log

Looks like it might have something to do with the egg (python3.10.12 installed, both machines) and/or setuptools:

Thought there was a link for static builds, found the line:
"Github Repository (for developers, not for installing)"

which directly contradicts

gaubert/gmvault/README.md:
"You can also install the software from the source from (github.com/gaubert/gmvault)."

Here's the cleaned log of that attempt.
