Two different systems - one AIX 7.2.2.1, the other AIX 7.1.5.1

Initially failed to install because bos.net.sctp was not installed (appears to be optional fileset, I can't find any production servers with it). 

Installed fileset from OS repo (NIM server) ... rpm still fails to install for a "missing library" that is installed.

You need to run "updtvpkg" command whenever you install rte/installp filesets. That way rpm database will get updated.

So - this was a command I was unaware of, and it seems to resolve the issue nicely.  But where is this documented (other than ftp://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox/FAQ.txt - which I only just found today)?
