An installation package that checks for a certain previous version of an application, then installs the changed files/directories, is an effectively an updater and is certainly possible with PackageMaker. If you mean something that actually patches files ala diff/patch, then, no, you can't do that easily with PackageMaker (you _could_ with a postflight script, but that's really violating the spirit of install packages) I can't run on Leopard to check this but I tend to remember that there is a patch feature in PackageMaker 3.
