I get a lot of parse warnings about scaling by 0.
I've searched for "scale" through the entire file and all the includes, and
can't find any "bad" scalings.  Does this behaviour happen when a single scale
value like scale 5 is automagically promoted by POV-Ray to scale <5, 5, 5> ?
I'm just trying to clean up the code so that I have a "clean" message window and
therefore an easier time debugging ongoing scene development.

It would be helpful to quote the offending line's text, or line number (harder
to do with includes?).

I could also use a hand figuring out exactly what the camera error means.

Parse Warning: Camera location to look_at direction and sky direction should be

No, it happens when you try to scale along a particular axis using:

     scale y*N

because from POV-Ray's syntax this is equivalent to

     scale <0,N,0>

which would make the thing a flat pancake, so POV-Ray presumes that what 
you actually meant was

     scale <1,N,1>
