Thanks much for the explanation! One more question. I suppose if I install the various minor versions on different disks (e.g. I want 3.3.2 and 3.3.3 as well), that would work fine as well, and I don't even need pkgutil --forget? Or am I missing something?
You can install in different locations. I have never tried using different 'volumes' (in Apple parlance), but AFAIK Apple treats them separately (with separate records of packages installed).
