Recent Gentoo update removed another bit of Ruby 3.0 support:
  • virtual/rubygems lost ruby_targets_ruby30 USE flag
  • dev-ruby/bundler lost ruby_targets_ruby30 USE flag
  • ruby-ng.eclass added ruby30 to "removed implementations"
  • ruby-utils.eclass lost ruby30 in RUBY_TARGETS_PREFERENCE
This causes 

masked by: invalid: DEPEND: expected: dependency string, got: ')',
token 15, invalid: RDEPEND: expected: dependency string, got: ')', token 15)
errors for our gitlab ebuilds.

Since GitLab still works on the migration to Ruby 3.1 (see https://gitlab.com/groups/gitlab-org/-/epics/10034) I had to add the old versions of the ebuilds/eclasses to the gitlab overlay.

In addition you have to a) unmask the ruby_targets_ruby30 USE flag for virtual/rubygems by adding 


  =virtual/rubygems-17 -ruby_targets_ruby30
to /etc/portage/profile/package.use.mask (note the '-' here; its a kind of double negation).

b) set the ruby_targets_ruby30 USE flag for virtual/rubygems by adding 


  virtual/rubygems ruby_targets_ruby30
to /etc/portage/package.use/<your file>
