DaveH But I have to say that if I was a noob I'd find the instructions very confusing
Can only agree. Unfortunately, it seems a common problem with FOSS-software these days, that - as helpful as the people may be, and here they are most helpful, thanks a lot! - projects seem to be seen from the perspective of the insider.
As a newbie here, I ran into similar stuff (Forbidden, no scan, installation, ... ). Without perseverance, I wouldn't have managed.
For those involved, sometimes it seems to be forgotten, that there are plenty of potential users out there, who simply want to install, apt...something, and run a software. Not recompile, debug symbols, whatnot. Just fire and forget.
Therefore my suggestion of further up, which is still somewhat difficult to the non-*nix user, but doable.
