The order in which you do things matters. NKFlare wants to use variables
like "cam_loc", "light_loc", and a pile of stuff that's created in the flr
file, so you have to declare those variables before the #include, and call
space2.flr before nkflare.inc.

Like this:-

#declare cam_loc = <0, 0, -1000>;   // use the x, y, and z of your camera
#declare light_loc = <0,0,0>;       // use the x, y, and z of the light
                                    // you wish to flare
#declare lookat = <0, 0, 0>;        // the look_at vector of your camera
#declare sky_vect = <0,1,0>;

#include "space2.flr"
#include "nkflare.inc"
