Hi,

I originally added dev-libs/gumbo because it was a dependency for dev-
ruby/nokogiri, but in the mean time nokogiri has bundled this package
and modified it to fix various issues and better integrate it with
nokogiri.

Google's upstream version appears to be no longer maintained, it has
been archived since 2023-02-15.

This package still has some reverse dependencies:

  app-text/mupdf
  dev-perl/Alien-LibGumbo
  dev-qt/qt-creator
  mail-client/claws-mail

There are no open bugs for it in Gentoo.

Hans
