using a specific version of setuptools lead to distutils.errors.DistutilsSetupError: each element of 'ext_modules' option must be an Extension instance or 2-tuple

[pbiering]

What I did:

bundle zope.i18nmessageid together with mailman3 for EL8

Because of some other dependencies this requires a specific version of setuptools to build the bundle

What I expect to happen:

Working

What actually happened:

Exception

distutils.errors.DistutilsSetupError: each element of 'ext_modules' option must be an Extension instance or 2-tuple

What version of Python and Zope/Addons I am using:

At least with 6.0.1, 6.1.0 and 7.0

Found well-known root cause here: https://stackoverflow.com/questions/21594925/error-each-element-of-ext-modules-option-must-be-an-extension-instance-or-2-t

And the proposed fix would be reordering the imports:
