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.
