virtualenv bundles a local copy of pip. And that pip in turn vendors distlib. So you'd need to build a new pip wheel with your customised version of distlib vendored in it, and then build virtualenv with that version of pip embedded. (You can avoid the last step by putting the new pip wheel in a virtualenv_embedded directory next to virtualenv.py, but you'd have to check the docs and maybe sources to ensure I remembered that right. Also your pip wheel would need to be a higher version than the embedded one, or it would get ignored). Paul -- https://mail.python.org/mailman/listinfo/python-list
