These programs are inherently limited by their databases of programs. If they don't know about a particular program they can't check for updates for it.
That said, as mkrishnan mentioned, those two DO work.

MacFreewareUpdates is a little hit or miss, but it does catch lots of things. VersionTrackerPro is probably better, since their database is so extensive. It's very hard though, without a standardized distribution system, and MacFreewareUpdate is much better at finding updates than it is at installing them. Because likewise, there's no standardized way in which the image or zip files arrive to your computer. Which is why what you're asking for is essentially cakewalk on most Linux distributions but it doesn't really practically exist on Macs or in Windows....
