The test suite of setuptools_scm has a test which utilises pip and which fails if pip is not found.

```

(In my case pip was only installed for PYTHON_TARGETS python3_4 but not python3_6).

Installing dev-python/pip for the correct PYTHON_TARGETS solves the problem.

Suggestion add "test? (dev-python/pip[${PYTHON_USEDEP}])" or similar to DEPEND.
