Subject: [PATCH 1/2] Do not pin dependencies to specific versions

Because the packages in `setup.py` are really old and they use exact
version, when installing the package into a virtualenv it will end-up
downgrading already existing  packages.

In the Python documentation it is also mentioned that it is not a best
practice to use `install_requires` to pin dependencies to specific versions.
