you should read the first lines of greebles.inc, it says:

// Greeble-macros and utilities
// for some weird reason, these don't function properly in POV-Ray 
3.6.1, but they work fine in MegaPOV

the problem, as far as I can tell, is that some greeble-cells get too 
small for POV-Ray, causing an error in the official version when I try 
to create a polygon for that cell.  MegaPOV probably just ignores those 
polygons.
