Thanks, that helps it get a bit further, but it spits out a whole truck
load of errors before it gets anywhere near DRM stuff.  Either this
stuff isn't maintained, or it's for a newer flavour of TEX.  From what
I read on the web, this kind of problem is fairly typical where TEX
stuff goes (no two tex versions are compatible.)

I think I'll leave the kerneldoc stuff to someone who knows (a) how to
deal with it.
