I believe there's something wrong with your rubygems, can you try a clean Kali install?
iostruct (0.0.4)
zpng (0.3.2)
from zsteg.

I've just tried fresh Kali VirtualBox image, and it worked just fine.
btw, why you installed with --force flag?
Try to remove gems iostruct & zsteg and reinstall zsteg without --force flag.

Peculiar!
Uninstalled (iostruct & zsteg) and reinstalled (zsteg 0.24 without --force flag) and the following happens:
/var/lib/gems/2.7.0/gems/zpng-0.3.2/lib/zpng/string_ext.rb:7:in `block (2 levels) in <class:String>': undefined method `color' for #<String:0x00005618bf08ad80> (NoMethodError)

Sounds about right, moved all files and started from scratch - now it works!
Thank you for your time & help!
