How about providing a tool=20 that scans all binaries in the standard locations for what libs they=20 depend on, and also allows the user/admin to specify the paths to=20 binaries that he installed on his own, then outputs a list of unused=20 libraries? This could be just another ports-mgmt tool (and=20 incidentally, I've written scripts that do this several times already=20 (none of them are worthy of publication though, they're just quick=20 hacks)).
