Hi, and thanks for helping.
Yes, I set a root password and use that to set everything up.
PIP installed fine (I did re-install using your instructions, which also worked fine). My knowledge level is very low with linux, most of what I have done I have learnt from other forum posts, so I am not sure I even need all of the things I am doing - I just know that they worked fine is Raspbmc.
Moving to OSMC has meant changing a lot of my backed up files so that paths point to the right place. I now have everything else working except this. I appreciate this is not something most people would mess around with, but would really like to have everything working as before.
