According to the man page mkillum does not work for cylinders (it  
works for
spheres, though, but there is no point in creating a sphere to  
simulate the
sky).

Perhaps you could use Radzillas 'ghost' material. IIRC that was a  
material
that was visible but did not influence the lighting calculations. If  
this is true
you can create a cylinder around your scene without compromising the sky
distribution.
