I would suggest removing the pump and checking it and replacing the gasket if the water pump is good.

The water pump pulley and shaft should not have any lateral movement, or wobble. If it has any, it needs to be replaced. My experience has been, if the pump is leaking, it'* bad. Considering the amount of time and effort required to remove the pump (here'* a link to autozone'* instructions)

http://www1.autozone.com/servlet/UiB...3d8015dc18.jsp

you may want to replace it once you get it off. First, be sure it is the pump that is leaking. As I recall, there is a bypass hose just above the pump that connects to a plastic fitting in intake manifold (I believe) that often cracks and leaks.
