Immediate failures, obscuring the real problem:

FAILED tests/unit/create/via_global_ref/test_build_c_ext.py::test_can_build_c_extensions[venv] - AssertionError: assert 1 == 0
FAILED tests/unit/create/via_global_ref/test_build_c_ext.py::test_can_build_c_extensions[cpython3-posix] - AssertionError: assert 1 == 0
FAILED tests/unit/seed/embed/test_bootstrap_link_via_app_data.py::test_seed_link_via_app_data[False] - AssertionError: assert not 1
FAILED tests/unit/seed/embed/test_bootstrap_link_via_app_data.py::test_seed_link_via_app_data[True] - AssertionError: assert not 1

Underlying problem is that the test suite is trying to run this command to install external software during the test:

cmd        = ['/tmp/pytest-of-riastradh/pytest-14/test_can_build_c_extensions_ve0/env/bin/pip', 'install', '--no-index', '--find-links', 'https://pypi.org/simple/setuptools/', '--no-deps', ...]

Fortunately it is caught by our http_proxy hack:

  1 location(s) to search for versions of setuptools:
  * https://pypi.org/simple/setuptools/
  Fetching project page and analyzing links: https://pypi.org/simple/setuptools/

>How-To-Repeat:
cd devel/py-virtualenv
bmake test
>Fix:
Yes, please!  If there is a way to run the test without network access, e.g. by using the setuptools package we already have, that would be best.  If the test can't run without network access, but there is a way to disable it, that would be second-best.  Otherwise it might be a matter of asking upstream about how to make their test suite work network-disconnected.
