Disksuite 4.2.1 wont install via jumpstart on Solaris 8 2/04

Question

Trying to install Disksuite on a Sun Solaris 8 image. The install works on Fujitsu hardware with an even older (2/02) Solaris 8 image for Fujitsu hardware, but for some reason its not working for a Sun V120 with Sun's 2/04 solaris 8 release.
Here's the output from my finish script to install the packages. All other packages install just fine.

The FAQ mentions this with respect to patches, but it can affect packages as well:
