couple of questions about the setup:

-m 16 ?  was that intended to be -j 16 ?

Those two would have to repeat the --prefix setting.  Was the above just
shorthand?

So can see this:


cd gui && python3 setup.py install --prefix
/builddir/build/BUILDROOT/rmlint-2.10.1-10.fc37.x86_64/usr --record
.files.txt
/usr/lib/python3.11/site-packages/setuptools/dist.py:519: UserWarning:
The version specified ('2.10.1 Ludicrous Lemur') is an invalid version,
this may not work as expected with newer versions of setuptools, pip,
and PyPI. Please see PEP 440 for more details.

aside from the setuptools complaint, that looks ok, no? the "setup.py"
line has on execution expanded to a path ending in /usr, not /usr/local

What am I missing?
