The upstream solution has this problem, too. In fact, this approach will be much closer to the upstream solution in the sense that it uses prebuilt wheels to install/update virtualenv. The wheels will just come from different packages than python3 itself. IMO it'd be sufficient to place a README file into the ensurepip/_bundled dir that would explain this. Actually, diverging from upstream in this way is an argument for not doing the "files copying" solution now. While trying to create the patch that would rebuild the wheels from system and install them in venv, I bumped into few ugly problems, which is why I came up with this "wheels in RPMs" solution in the first place. I'd like to do this for 3.4 in Fedora and then start working on the "file copying" solution that would be acceptable for upstream Python 3.5.
