Melanie is CORRECT
the circuit is designed wrongly. Forget the micro. Even by connecting the ground at anode of LED it would not light. the LED woud have been wired otherway round. this configuration is like a protection diode across a relay coil driven by a transistor. Perhaps XOBX has to improve on his / her funda of harware design.
YES, it will light, if by using the port pin RB0, we switch a higher voltage than +6.4V to the anode of LED.
