Hi Martin, Sorry, I did forget to put all that in, still learning including how to use a list for help. Right - I have it on a VM running Archlinux (4.8.13-1 - I only started a week ago) and I used pacman to install the package gnuradio 3.7.10.1-3. At that point after installing the gnuradio package I had to go and fetch extra packages (gtk2, gtk3, python-lxml and python2-cheetah) to make the grc work. I am not sure if maybe I should have explicitly installed gnuradio-companion? But once I'd installed the extra packages it worked fine - until I started the python programming part.
