#63383: pipenv sourcing from its own virtualenvs

---------------------+--------------------
 After recently updating to the latest pipenv 2021.5.29 I am unable to use
 pipenv on the command line. It appears to be sourcing packages out of the
 virtualenv maintained by pipenv, which lacks the
 `backports.entry_points_selectable` package and can't be launched.

 This is with a fresh virtualenv (after `pipenv --rm; pipenv sync`):

 However, to get it to work, I can explicitly use the MacPorts system
 installation:
