The last part seems to be the catch here. How about providing a tool that scans all binaries in the standard locations for what libs they depend on, and also allows the user/admin to specify the paths to binaries that he installed on his own, then outputs a list of unused libraries? This could be just another ports-mgmt tool (and incidentally, I've written scripts that do this several times already (none of them are worthy of publication though, they're just quick hacks)).
