You didn't miss anything - I think there are some bugs
I did some testing with persistent animation on using

#version unofficial MegaPov 0.5;//or 0.4 for the wmp0.4 test
light_source{5, rgb 1 }
camera{location 5 look_at 0 }
#ifndef(done)
#warning "parsing started\n"
sphere {<0 0 0>, 1 pigment{rgb 1}label sph}
#declare done = 1;
#warning "parsing ended\n"
#end

wmp0.5a doesn't work properly - maybe a bug in how variables are treated - looks
like they are killed after each frame - aren't they supposed to live until the
last frame has been traced
wmp0.5 works as expected as does wmp0.4

So either just use wmp 0.5 for your anim or ask Nathan to fix this & release
MegaPOV 0.6 :)
The first option is probably better at this time as he is supposed to be busy with
"life" or something

Also Nathan if you read this why aren't lights allowed to be persistent - they are
treated as objects in every other aspect (and the camera for that matter and
anything else you care to throw in)
