Why can't my LED light up with the Arduino Xbee Shield

Hello everyone,
I am facing a problem of my LED not being able to light up when i connect the Arduino Xbee shield on my Arduino Uno. Can some one help me with it? When trying to light the LED up with the Sparkfun Breakout board, it do light up.

This is something you need to bring up to the manufacture of the board and your Arduino.
