This broke ‘tests/guix-pack-relocatable.sh’ for these reasons:

--8<---------------cut here---------------start------------->8---
+ guix pack -RR python-numpy python-scipy --no-grafts -n
guix pack: error: profile contains conflicting entries for python-numpy
guix pack: error:   first entry: [email-masked] /gnu/store/i1g6wbcc0ilhcc5vy4pi70z58gk1716f-python-numpy-2.2.2R
guix pack: error:   second entry: [email-masked] /gnu/store/2s1jala0jg56drh4hc19mrdg6w3gswhm-python-numpy-1.24.4R
guix pack: error:    ... propagated from [email-masked]
guix pack: error:    ... propagated from [email-masked]
hint: Backtrace:

Would be nice to address it before we get a deluge of angry bug reports.
