You're operating at "gimbal lock" here (see "Apollo 13" for the dangers
associated with this condition :P) by looking straight down on your scene,
confusing POV-Ray's standard way of determining what coordinate system you want
and such.
Explicitly specifying both "direction" and "sky" should fix the ambiguities
POV-Ray is facing. You'll probably want "sky z" and "direction -z".
