Taking this from:
http://trastle.github.io/rpi-weather/gettingInstalled.html
sudo apt-get install libusb-1.0.0 python-usb python-crypto python-paramiko gnuplot gettext sphinx-common
mkdir ~/weather
cd ~/weather
git clone https://github.com/jim-easterbrook/pywws.git
cd ~/weather/pywws
make
python setup.py build
sudo python setup.py install
I've also moved the folders around so the pywws buillt output lives in /home/pi/weather
Add the crontab (also in repo)
