If the gravity interacted with light in Newtonian way, you would need the mass of a moving photon. However, supposing its mass is nonzero, you should get it decelerate, when receding from a body with mass. This makes v not equal to c, denominator is no longer zero, the mass of photon computes to zero, and the Newtonian gravitational force acting on light turns to zero.
Why does the light appears to interact with massive bodies after all - that's the sign a new explanation is needed. One that doesn't depend on the mass of photon.
