Your differences are entirely in var/mason_data, aka the Mason cache.
This confirms that you skipped the last bit of step (6b) in the
README[1]:

        6b) If you are UPGRADING from a previous installation:
        [...]
              Finally, clear the Mason cache dir:
        
                  rm -fr /opt/rt4/var/mason_data/obj
        
              You may then start your web server again.
