Indeed. And once I make my change, PYTHONNOUSERSITE gets also placed in
the wrapper of the `pip` executable.

I am attaching the patch file.
I was trying to test with
./pre-inst-env guix shell -C --network --no-cwd python-xmldiff coreutils python-pip
pip install xmldiff==2.4
echo > ~/.local/lib/python3.10/site-packages/xmldiff/main.py
xmldiff --help
Without my patch, we get an error on 4th line. With my patch, we get
the "Read-only file system" error on the 2nd line
Best,
Wojtek

Subject: [PATCH] guix: build: python-build-system: Don't process user site dir
* guix/build/python-build-system.scm (wrap): Define PYTHONNOUSERSITE for
programs so they don't incorrectly pick up local, pip-installed libraries.
