Try specifying the light's position/direction before calling gluLookAt(). The reason is that the light's position/direction is transformed by the modelview matrix, so if you don't want the light to move, specify it's position/direction before applying any transformations.

You might also want to take a look here. It has good explanations and related code snippets.
