The test suite of setuptools_scm has a test which utilises pip and which fails if pip is not found. ``` testing/test_regressions.py::test_pip_download FAILED ============================== FAILURES =================================================================== ____________________________________________ test_pip_download ______________________________________________ tmpdir = local('/var/tmp/portage/dev-python/setuptools_scm-1.15.6-r1/temp/pytest-of-portage/pytest-8/test_pip_download0'), monkeypatch = <_pytest.monkeypatch.MonkeyPatch object at 0x392db21a160> @pytest.mark.issue(164) def test_pip_download(tmpdir, monkeypatch): monkeypatch.chdir(tmpdir) subprocess.check_call([ sys.executable, '-c', > 'import pip;pip.main()', 'download', 'lz4==0.9.0', ]) ../../../../work/setuptools_scm-1.15.6/testing/test_regressions.py:57: _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ popenargs = (['/usr/bin/python3.6', '-c', 'import pip;pip.main()', 'download', 'lz4==0.9.0'],), kwargs = {}, retcode = 1, cmd = ['/usr/bin/python3.6', '-c', 'import pip;pip.main()', 'download', 'lz4==0.9.0'] def check_call(*popenargs, **kwargs): """Run command with arguments.

Installing dev-python/pip for the correct PYTHON_TARGETS solves the problem. Suggestion add "test? (dev-python/pip[${PYTHON_USEDEP}])" or similar to DEPEND.
Old version removed. Please reopen if it still happens.
