I just installed Camllight and I encountered the problem as you. Because the 
type menu is just a shorter name for the complete type (string * string) list, 
you have to use:
type menu == ( string * string ) list ;;

(with two '=' signs)
I don't know the exact rule about this. It might be close to the difference 
between 'type' and 'data' in Haskell.

Good luck!
