"No version for 'optional' dependency..." when updating Solaris 11.3 on Intel hardware

I'm having trouble updating Solaris 11.3. The problems below show up on both a DL360 G5 hardware (dual Xeons), and a VM guest (Core i7). The Solaris installations use Sun's image, and I did not perform any customization other than to enable their Software Repository for Sun Studio.

Searching for some of the error messages is not producing anything useful.

What is the problem, and how do I fix it?
