I explicitly have ruby-3.1 unmasked with "=dev-lang/ruby-3.1.2-r1  
~amd64" in package.accept_keyword, and USE_RUBY="ruby31" in make.conf.   
I do not see any reference to ruby in the profile.  Is there somewhere  
else I need to unmask something?  emerge --info also says  
'RUBY_TARGETS="ruby31"' as its only reference to a specific ruby  
version.

As I said in my reply to Neil, why would this happen in just a handful  
of packages, but not in over thirty others?  mini_mime is the other  
problem package, and it does not use ruby_add_bdepend so there is only  
one line with USE_RUBY:  'USE_RUBY="ruby26 ruby27 ruby30 ruby31"'.

So - why is ruby31 disabled for (so far) only these two packages?    
(The other packages which are failing depend on one of these two.)
