rm: gentoo sandbox violation when emerging certain python packages

[elde-n]

When replacing GNU rm with uutils-rm (cp /usr/bin/uu-rm /usr/bin/rm) I get an error when emerging certain python packages.
However when replacing GNU rm with busybox-rm everything is fine.

1. su
2. echo "sys-apps/uutils-coreutils ~amd64" >> /etc/portage/package.accept_keywords/uutils-coreutils
3. emerge "=sys-apps/uutils-coreutils-0.0.28"
4. rm /usr/bin/rm
5. ln -s /usr/bin/uu-coreutils /usr/bin/rm
6. emerge dev-python/pip

Sorry, i meant some simple commands with rm and the other steps that triggered the issue
not something that requires installing Gentoo.
