Re: Problem building python3-flit_scm for use with borgbackup

Good news. After a few varying attempts I have successfully built 
python3-flit_scm and python3-exceptiongroup using the python build and 
pip install commands.

I have then installed the addon packages on my vm testbed and confirmed 
that the fuse mount command works again with borgbackup.

I will look at using the python build/pip install approach on all the 
python modules for borgbackup as setup.py is flagged as deprecated. If 
that all works then I will submit a patch set for the bug fix.

Learned a lot with this bug issue. Hopefully useful for the future.

Regards,
Adolf.

I will give it a go and see how it goes. I will also compare it with the python3-flit module we have because that looks to use the pypproject.toml file, although there are several environment variables defined that I am not sure how to specify for my case but will see how things go.
