This didn't quite work for me - dpkg complained about "no path found matching..." for every library. I replaced the "$path" in the dpkg command with "${path##*/}" to just match the library name. Further inspection showed my package manager installed libraries to /lib (a soft link to /usr/lib/) but lsof returns files in /usr/lib.

Other than that it seems to work - i.e. no alarming output. :-)
