You will need to have Nmap installed. If you are on Debian/Ubuntu, this should do all the work:
$ sudo apt-get install nmap
On OSX you can install with Homebrew or macports:
$ brew install nmap
$ port install nmap
Once you have Nmap installed, install dependencies from the
$ pip install -r requirements.txt
If the project get some stars, I will upload it to the The Python Package Index.
