Thanks - I will see about getting support from RHEL.

I am the author of the program and rpm.

The dependencies are added using a scripted series of commands to extract the dependency from the ldd output and locate the packages which provide them. I suspect that this is the culprit, although I have tested it and a) it works fine on RHEL 7 and b) appears to produce the same output for RHEL 8, but something is obviously amiss.

I'll go and recheck that script more carefully.

Thanks for the info, and my apologies for the intrusion.
