Coming from a UNIX engineering perspective:

If your software ever tried to update other packages in this way, I would uninstall it, create an incident, and bring my legal team together to get you sued out of existence.

You handle YOUR software. You manage your own paths, and bring your own stuff to the party. If you update components on another person's system, you risk breaking it, and costing them a tremendous amount of money and pain.

That will translate into YOUR pain. Don't do it.

Manage your software, not theirs.

What you should do, is follow current best practices:

Create an installer that VERIFIES the minimum versions of software as provided by the OS. You can do that with apt, rpm, yum, whatever. When your vetting is done, you then issue message to the console, or via a log, etc that the system has been verified and may continue, and the installer continues, or that they are missing the per-requisites, and list them. By NO means should you go and get them. That is asking for trouble. You are a vendor, not a systems administrator.

NAME

     repair_packages -- verify or repair filesystem permissions and flags for packages.

SYNOPSIS

     repair_packages [arguments]

DESCRIPTION

     repair_packages is used by Disk Utility to verify or repair permissions on installed packages.

ARGUMENTS

     --volume	   Perform all operations on the specified volume or home directory.  The root volume '/' will be used if unspecified.

     --list-standard-pkgs
		   Output the list of package-id strings corresponding to receipts in the installer's receipt database that will be verified or
		   repaired by the --standard-pkgs flag.

     --verify	   Verify the specified package(s).

     --repair	   Repair the specified package(s).

     --pkg package-id
		   Add the specified package to the list of packages to verify or repair.

     --standard-pkgs
		   Add the standard packages to the list of packages to verify or repair.  Use --list-standard-pkgs to view this list.

     --output-format #
		   Use a special output format selected by #. Different output formats may be optimized for human or machine readability. The
		   default output-format is '0', and is a verbose, human-readable format.

NOTES

     repair_packages only runs on 10.6 or later systems. To verify or repair permissions on earlier systems, reboot with a Tiger or Leopard system
     disk and verify or repair permissions with the repair_packages version on that disk.
