i prepared a 2.0.1 which fixes the whl, if you confirm, i release it soon:

    pip install -i https://devpi.net/hpk/dev/ -U tox

should install you a wheel with tox==2.0.1 and properly required argparse.

(the reason this didn't appear in my release testing was because i use pytest and
it already includes argparse on py26 so no problem occured -- i now added
a bare tox section that just runs "-h" ...)
