[Distutils] Multiple pips to go along with my multiple Pythons

[Skip Montanaro]

Thanks for the responses. I eventually decided to just download and
expand the tarball, then execute

PY setup.py clean -a
PY setup.py install

for each of my PYs. I then deleted the pip, pip2 and pip3 items,
leaving only the pipXY versions. That avoids any confusion. While it's
a bit more work on my part, it achieved the desired result - nothing
but a bunch of unambiguous pipXY programs.
