Tools like pip, which depend on a specific Python version are fundamentally
flawed on *nix.  There's healthy debate in many upstream forums about this
issue.  Basically, nobody likes distributing things like pip3.4 and pip3.5,
etc.

If you install python3-pip you will get a pip3 but even that isn't great.
While having a command like `pip3` or `pip3.4` might seem like a useful
convenience, really the best way to invoke pip for a specific Python version
is to use `python3.4 -m pip` or `python3.5 -m pip`.  This goes for a small
handful of other packages like nose (with scripts like `nose2-3.4` being the
worst offenders!  better to use `pythonX.Y -m nose2`).

We're looking at ways of making this better and more consistent across all
Linux distributions.

Bug description:
  Hello,

  I noticed the following

  # fails
  python3.4 -m venv --clear python-venv
  Error: Command '['.../external/python-venv/bin/python3.4', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1

  # works, but no pip
  python3.4 -m venv --clear --without-pip python-venv

  Thank you
