What's the rest of this output, it should list the packages and files
involved.

Something appears to be asking for an old Ruby, hopefully the output will
show why.

Also, what does emerge --info show for RUBY_TARGETS and do you have a
setting for it in make.conf?

There is no rest. I can give the whole output for the last emerge
command which ended with the above line. Doubt that will be helpful.

Sadly there is no more output. Even 'emerge -v @preserved-rebuild' does
not give more.

No.

Could you also take a look at the file
/var/lib/portage/preserved_libs_registry ?

It's like this when there are no preserved libs:

# cat preserved_libs_registry
{}

I'm currently running 'find . -name '*preserved*' on / in the hope of
finding the set with the preserverd libs *g* Well, I will let it continue.

To me this reads as readline-7.0_p3 depends on libs from readline-6.3.

Smells a bit as some sort of bug. Try rebuilding readline?

This didn't happen here when readline was bumped.

That's what I hesitated to do in fear of blurring clues. Done.

Hrm. Replacing the obviously corrupt preserved_libs_registry with the
clean one from my backup? That would be the end of the investigation.

You could also check if those readline-6 preserved libs really exist:

/lib64/libreadline.so.6.3
/lib64/libreadline.so.6

Try renaming them or backing them up somewhere else and see if realine 
applications (bash) still work fine after that.

Other than that... I'd fill a bug about this ;)

This is no bug here. It's just storing the fact that it preserved these
/lib64/libreadline.so.6{,.3} under the replacing newer version package.
That is, readline-7.0_p3 now owns these files, but based on this
registry, they will be deleted and removed from its CONTENTS, once
there are no more consumers of it based on essentially NEEDED.ELF.2
contents in the VDB (/var/db/pkg/*/*/NEEDED.ELF.2).
That is, what is keeping them from being removed is not stored in this
registry.

Maybe there is just an old ruby:2.1 SLOT installed, that hasn't been
properly depcleaned?

Indeed.

i5-64 /home/hafi # emerge -p -c
[...]

 dev-lang/ruby
    selected: 2.1.9
   protected: none
     omitted: 2.2.9

[...]

After depclean, which required another @preserved-rebuild, a successful
one, I replaced the the now preserved_libs_registry with the problematic
old one. This time there was no problem.

Thanks for the in-depth explanation. Do you think that revdep-rebuild would've 
helped here?

And a bit off-topic for this thread (but it's a subject that interests me): 
does the preserved rebuild feature track user installed programs (outside of 
portage control)?
