dbus footprint mismatch

I am trying to install firefox 3.0, and it apparently depends upon dbus (among other packages.) I receive a footprint mismatch reading as follows: ============> ERROR: Footprint mismatch found: MISSING -rwsr-x--- root/messagebus usr/lib/dbus/dbus-daemon-launch-helper NEW -rwsr-x--- root/root usr/lib/dbus/dbus-daemon-launch-helper I understand the concept of the footprint mismatch, however I have not been able to find an explanation of exactly what the above 2 lines mean. MISSING is what? NEW is what? also what is the 2nd field root/messagebus and root/root...that is where the difference resides. Is that owner/group? Also, how do I continue with this install? Thanks
