# 2.4.0 is the latest release and publishes no wheel, so pip builds it from
# the sdist through the legacy setup.py path, using whatever setuptools is
# already installed.  Debian and Ubuntu's packaged python3-setuptools fails
# that build with "AttributeError: install_layout"; installing into a
# virtualenv avoids it.  See "Running the test suite" in docs/contributing.rst.
