Thanks guys, you have been really helpful.
whenster - I guess installing 0.6.2 is easiest. I don't know what new features or bug fixes I'd be missing by doing that but its worth considering.
DiapDealer - I'm not that technically knowledgable about Linux to know what some of what you said means, I'm afraid. Could you expand what you meant when you said this, please? "
I'm tempted to say you may have problems if you wanted to redistribute such a thing..."
Albert - Yes, it does help and might be the best compromise. I've only just discovered Sigil but I've read about it in at least two books on e-publishing and they rave about it. On that basis it seems a pity to leave out such a good tool, doesn't it?
