Since the initial issue is fixed, I close the issue.

You can revert my change if a new pip version works (again?) without ctypes.

STINNER Victor added the comment:

I pushed a workaround to limit the number of failures on the  OpenIndiana 
buildbot. Feel free once pip runs without ctypes and pip is updated in CPython.

These checks look low level, so it makes sense to use ctypes for that.

> Worst case we can just conditon that check on ctypes existing.

Do you mean skipping the new "manylinux" thing if ctypes is missing? If yes, I 
agree with this option. In practice, types is only missing in very rare cases.

[issue26610] test_venv.test_with_pip() fails when ctypes is missing

[STINNER Victor]

New submission from STINNER Victor:

pip/pep425tags.py requires ctypes, but it's not available on the OpenIndiana 
buildbot. I suggest to skip the test if ctypes is missing.

I don't know if it's possible to modify pip to make ctypes optional again.
