`dir' was meant above to be replaced by some specific directory that
you pick.

So, if "testit.scm" is in the directory "/home/cho/stuff", then the
specific directory you want is

 (build-path "/home/cho/stuff" "compiled" "native" (system-library-subpath))

and change "testit.scm" so it contains

 (module testit mzscheme
   (require "example.scm")
   (display (fact 3)))
