 Steps to reproduce from a clean install of MacPorts-2.8.0-12-Monterey.pkg

 $ sudo port select --set python3 python39
 $ sudo port install pipenv
 $ pipenv --help
 }}}

 Output:
 {{{
 Traceback (most recent call last):

 pipenv.patched.pip._vendor.pkg_resources.ContextualVersionConflict:
 (distlib 0.3.5
 (/opt/local/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10
 /site-packages), Requirement.parse('distlib<1,>=0.3.6'), {'virtualenv'})
 }}}
