IMPORTANT!  Nokogiri builds and uses a packaged version of libxml2.

If this is a concern for you and you want to use the system library
instead, abort this installation process and reinstall nokogiri as
follows:

    gem install nokogiri -- --use-system-libraries

If you are using Bundler, tell it to use the option:

    bundle config build.nokogiri --use-system-libraries
    bundle install

However, note that nokogiri does not necessarily support all versions
of libxml2.

For example, libxml2-2.9.0 and higher are currently known to be broken
and thus unsupported by nokogiri, due to compatibility problems and
XPath optimization bugs.
