This is an auto-filled bug because dev-ruby/selenium-webdriver installs files with broken symlink. The issue was originally discovered on arm64, but it may be reproducible on other arches as well. If you think that a different summary clarifies the issue better, feel free to change it. Attached build log and emerge --info.
