Re: python: setuptools version doens’t match guix package version / packaging python-ipydatawidgets

["Théo Maxime Tyburn" <theo.tyburn@gmail.com>]

I managed to package "python-ipydatawidgets" in the end. I just added
"python-setuptools" to the inputs. So it was easy. I thought setuptools
is always present in the build phase of python packages, my
bad.

Though this still doesn’t clear this mystery about the version of
setuptools not being the right one...
