Not sure if I replied to this elsewhere, but the reason for PACKAGING
on AIX 5.3 is because it can be used on AIX 5.3 TL7 and higher
(including AIX 6.1 and AIX 7.1).

In short, the level an application in packaged on implies the lowest
level that application can be expected to run on properly. Sometimes
you can be "lucky" if you want to call it that, and run on a previous
TL. Personally, I consider that the exception - not the rule.
