For the scale by zero, they come from constructs like scale Value*x.
When that appen, Value*x get promoted to <Value,0,0> generating two
warnings because scale 0 is not allowed.
You need to edit the file to replace all scale Value*x by
scale<Value,1,1>, all scale Value*y by scale <1,Value,1> and scale
Value*z by scale<1,1,Value>
For the problem with math.inc, make sure that you don't pass nor
generate any null vector.
A nul or zero-length vector don't have any direction and can't be
normalised to an unit length vector.
You may try adding this:
#if(vlength(Vector)=0) #declare vector=<1,0,0>; #end
