It is expected because Setuptools removed the compatibility with Python 2,
see the ChangeLog:

--8<---------------cut here---------------start------------->8---
v47.0.0

28 May 2020
Breaking Changes

    #2094: Setuptools now actively crashes under Python 2. Python 3.5 or later is required. Users of Python 2 should use setuptools<45.
--8<---------------cut here---------------end--------------->8---

<https://setuptools.readthedocs.io/en/latest/history.html>
<https://github.com/pypa/setuptools/issues/2094>


The question is: do we remove ’python2-setuptools’ since it is defined
by the usual ’package-with-python2’?

--8<---------------cut here---------------start------------->8---
(define-public python2-setuptools
  (package-with-python2 python-setuptools))
--8<---------------cut here---------------end--------------->8---

Or do we define python2-setuptools with the version v46.4.0?  Which,
IMHO does not make sense since Python 2 is end of life since one year.


All the best,
simon

Currently, python-setuptools is at version 52.0 and python2-setuptools
at version 41.0.1.  Both build fine.  The comment says:

--8<---------------cut here---------------start------------->8---
;; Newer versions of setuptools no longer support Python 2.
(define-public python2-setuptools
  (package
    (name "python2-setuptools")
    (version "41.0.1")
--8<---------------cut here---------------end--------------->8---

therefore, this part of the bug is done.  Let check the other part.


Cheers,
