It looks like the PyPi Index hasn't been updated yet:
https://pypi.python.org/simple/PyFuzz/
(Output at time of writing):
PyFuzz-0.1.0.tar.gz
This is a known issue with PyPi - package indexes and mirrors for the actual packages are often out of sync, if not down alltogether. Usually its the other way round though - the index listing a version that some package mirrors don't have yet. http://www.pypi-mirrors.org/ may be useful to check mirror freshness.
So it's not a mistake on your side, but a failure of PyPi. Just wait, and eventually it should update and resolve itself.
What you can do in the meantime is to install the most recent version of your package by explicitely giving the URL to the source tarball:
pip install https://pypi.python.org/packages/source/P/PyFuzz/PyFuzz-0.1.1.tar.gz
