Well Smolin is not going right here. Newtonian gravity predicts light 
bending. It gives a half of the observed value.

http://en.wikipedia.org/wiki/Bending_of_starlight

Search for "In 1801 Johann Georg von Soldner had pointed out that 
Newtonian gravity predicts that starlight will bend around a massive 
object"

An usual way to compute light bending in galaxies is to apply MOND and 
then twice that value. Of course, this is a kind of trick. A better 
procedure is to use relativistic MOND theory.
