Subtle. Seems access to pip 3 is via
# python3 -m pip list | grep crypto
DEPRECATION: The default format will switch to columns in the future.
You can use --format=(legacy|columns) (or define a
format=(legacy|columns) in your pip.conf under the [list] section) to
disable this warning.
pycrypto (2.6.1)
So 3 seems to have pycrypto 2.6.1... maybe.
