Yes, this is the way things are. If you want to get around it, you can
(declare sum), and there are various macros available if you want to
go more whole-hog and declare things in reverse order.
For example:
(defmacro do-top-down [& forms]
(cons 'do (reverse forms)))
(do-top-down
(defn average [& args]
(/ (sum args) (count args)))
(defn sum [& args]
(reduce + args)))
