Exit code 81 on deploying serialized package (Production Premium CS6)

In trying to deploy a serialized package, I'm getting this error (exit code 81) when I try to it using installer (ie. installer -verbose -pkg /Volumes/AdobeProductionPremiumCS6_Install/AdobeProductionPremiumCS6_Install.pkg -target /)

I've also tried moving this package off a mounted disk image and running it directly from /Users/Shared. And of course, this is running with root privileges.

This package has all the AAMEE default options, as well as the AIR components disabled.

I don't experience this error when using a trial package, I'm only experiencing it with a serialized package.

Any ideas? Are these exit codes documented anywhere?
