initial thoughts:

- a quick hack would be to update the postinstall script so it doesn't matter if you try to run it more than once
- that postinstall script is confusing (why is it installing or chmod'ing files? why is it doing a launchctl load -w [we generally don't do that per policy]).

If there is a bug in the way we generate pkg or mpkgs that's causing the script to run too many times, that should be fixed.

pkgutil / pacifist?
