  # Ordinarily we would just the `doCheck` and `checkDeps` functionality

  # `mkDerivation` gives us to manage our test dependencies (instead of breaking

  # out `doCheck` as a package level attribute).

  #

  # Unfortunately `lit` does not forward `$PYTHONPATH` to children processes, in

  # particular the children it uses to do feature detection.

  #

  # This means that python deps we add to `checkDeps` (which the python

  # interpreter is made aware of via `$PYTHONPATH` – populated by the python

  # setup hook) are not picked up by `lit` which causes it to skip tests.

  #

  # Adding `python3.withPackages (ps: [ ... ])` to `checkDeps` also doesn't work

  # because this package is shadowed in `$PATH` by the regular `python3`

  # package.

  #

  # So, we "manually" assemble one python derivation for the package to depend

  # on, taking into account whether checks are enabled or not:
