Failed to install requests-kerberos using manual installation method

[Zorrom]

Tried installing request-kerberos using the following python command but it failed with the following error message
$ tar -xvzf requests-kerberos-0.12.0.tar.gz
$ cd requests-kerberos-0.12.0
$ python setup.py install

error in requests-kerberos setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers

Kindly assist on this

try updating your setuptools. I'm using a virtualenv, so I did the following before trying to install requests-kerberos:

./virtualenv/bin/pip install --upgrade setuptools
