In the files you attached there was no call to this function, and as I have not checked out the source I can't be sure, but apparently some macro calls LISTEN-TO-SYSTEM-MANAGER during its expansion.
Now normally macroexpansion happens before functions are loaded. Therefore a macro should normally expand without calling functions (but may of course include function calls in the generated expansion code).
When you really want to have a function to be available at macro-expansion time, you have to wrap the function in eval-when, like what now happens already with many functions in messaging.lisp:
(eval-when (:compile-toplevel :load-toplevel :execute) (defun LISTEN-... (..) ..) )
