Given everything below - what other reasons might there be for this?   
I've yet to find any pattern of the difference between the ebuilds for  
the small number of dev-ruby packages that show this problem, and those  
for the the thirty plus which have installed just fine.

Hmm.  It looks to me that line should probably be 'USE_RUBY="ruby26  
ruby27 ruby30 ruby31" ruby_add_bdepend "'  However, as it only affects  
the required ruby version for two depedencies only if the test use flag  
is set (it is not) I'm not sure why it would matter.

I suppose it is likely just a typo in the ebuild.  They removed ruby25  
from 1.1.0 but didn't add the newer ruby versions.  Actually even 1.1.0  
may be broken as it includes ruby30 in USE_RUBY but not on the  
ruby_add_bdepend line.  However, I just made an -r1 in my local  
overlay, adding the new ruby versions to that line, and I still get the  
same error.  So I'm actually still stuck figuring out why this ebuild  
won't take ruby31.

Why would I do that if I don't have ruby-2.7 installed, nor do I want  
to?

That I agree with.  If I knew then what I know now, I would have argued  
much more vigorously against using Ruby on Rails for this web site.   
But that's fodder another entire thread.
