It turns out to have been nothing too serious.  The oil pump was not
primed and therefore not able to pump any oil to were it needed to be.
What I did to remedy the situation was to fill the oil filter completely
with oil and restart the engine.  It worked.  There was enough pressure
behind the pump to provide suction to bring oil into the pump and be
pushed into the rest of the engine.

It works great now.

thanks for the replies.
