Unfortunately, we are living in an old system where the scripts and package are constructed with scripts not with package maker. So we don't have access to the Gestalt features of package maker, at least I'm not sure how to get to them without Package maker. The script is written in perl. I checked out the Mac::Gestalt package but it seems to be pretty out of date. No 64-bit support and gestaltSysArchitecture doesn't return anything on Intel. Maybe you can write a command line app that performs the gestalt, include it in the Resources sub directory of your installer package and call that from your script.
