bug#52906: python-biopython conflicts with python-numpy

[zimoun]

Hi,

Using 7022eb6, the package ’python-biopython’ propagates
’python-numpy’, i.e., python-numpy@1.20.3.

However, because Guix installs by default the last version and:

--8<---------------cut here---------------start------------->8---
$ guix package -A | grep 'python-numpy ' | cut -f1,2
python-numpy            1.21.3              
python-numpy            1.20.3              
--8<---------------cut here---------------end--------------->8---

then this manifests.scm leads to an error,

--8<---------------cut here---------------start------------->8---
$ cat /tmp/manifest.scm
(specifications->manifest
 (list "python-numpy"
       "python-biopython"))

$ guix package -m /tmp/manifest.scm -p /tmp/fail
The following packages will be installed:
   python-biopython 1.76
   python-numpy     1.21.3

guix package: error: profile contains conflicting entries for python-numpy
guix package: error:   first entry: python-numpy@1.21.3 
/gnu/store/ggrkk9l67fjn1cj7alr8vx40xv08a6h0-python-numpy-1.21.3
guix package: error:   second entry: python-numpy@1.20.3 
/gnu/store/wgsmkn68q8h178sqc7ywjcdr330z9rb6-python-numpy-1.20.3
guix package: error:    ... propagated from python-biopython@1.76
hint: Try upgrading both `python-numpy' and `python-biopython', or remove one of
them from the profile.
--8<---------------cut here---------------end--------------->8---

which is annoying.

I propose to refer as name “python-numpy” the symbol python-numpy which
leads to a consistent scientific Python stack.  And to refer as name
“python-numpy-next” the symbol python-numpy-next.

For instance, it is already the case for emacs-next or for the
Bioconductor package r-cistopic.

Doing so, adventurous people can use python-numpy-next (or recompile all
the scientific Python stack using it), or update it directly on master
(for testing say) without going to a core-update cycle.

WDYT?

Attached a proposed patch.

Cheers,
simon
