Happy St. Pat's from the MacGroup Five. (With apologies to Calvin and Jack for the bodies.)
Sometimes, bad things happen even when we're being careful. You know, like the time you accidentally threw out Mail.app and emptied the trash right away. Or you have a slight disk problem and somehow iChat has become corrupted. Maybe a program is acting oddly and you suspect a part of it is damaged. If any of this has happened to you, then one utility that might save you is Pacifist from CharlesSoft ($20 shareware). Pacifist will let you re-install a single program that came with your OS (10.3.9 and up for the current version, an older version is available for 10.2) like Mail that normally would require a re-install of the operating system. Of course, if you have that Time Machine or other backup, you should already be set…unless it's corrupt, or otherwise unusable, or the app that damages has files scattered all over and you don't know where they all are. You can also use it to install other package files.

Above is the start screen. You can open a PKG file or a ZIP, MPKG (metapackage), DMG, TAR, TAR.GZ, TAR.BZ2, CPIO, CPIO.GZ, CIPIO.BZ2, , and XAR files. That's pretty much every sort of compressed format you're likely to run into. You can even open them via URL, so you can use Pacifist to download a ZIP file, for example. You can then install the program from Pacifist.
