This error comes from meson, a good version, being found in ~/.local/bin/,
but meson_python not liking it (maybe it check for meson in some way that's
not working in this case). You can look at the source of meson_python to
find out the exact reason.

this is OK, it just tells you it could not find the tarball on a mirror,
but in the end it is able to get it, surely.

if you want to use pip-installed packages, and skip as much building of
them as possible, you need
to first run ./configure --enable-system-site-packages
However this still by default won't look in ~/.local/ for packages.
There are extra settings which enable this, but I don't recall from the top
of my head.
You can also do everything in a python venv, then
./configure --enable-system-site-packages will work without this extra hack
I forgot.
