pyvenv versus venv

    I have been so confused about pyvenv versus venv for virtual environments
    for Python3 that I shunned both of them.
    Also, pyvenv but not venv would work on one distro,
    and venv but not pyvenv would work on another distro.
    Now venv works on both distros.
    Also, "28.3. venv — Creation of virtual environments"[1] says:

        Note The pyvenv script has been deprecated as of Python 3.6 in favor of
        using python3 -m venv ...

    So "python3 -m venv /path/to/new/virtual/environment"
    is the way preferred by the Python Software Foundation.

    Unfortunately, venv is not happy on a Centos 7 installation:

        [doj at sbc ~]$ python3
        Python 3.4.5 (default, Nov  9 2016, 16:24:59) 
        [GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux
        Type "help", "copyright", "credits" or "license" for more information.
        >>> 
        [doj at sbc ~]$ python3 -m venv mobyvenv
        Error: Command '['/home/doj/mobyvenv/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1
        [doj at sbc ~]$ 

    so I resort to something like:

        virtualenv env -p `which python3`
