IMPORTANT NOTICE:

Building Nokogiri with a packaged version of libxml2-2.9.2 with the following patches applied: - 0001-Revert-Missing-initialization-for-the-catalog-module.patch - 0002-Fix-missing-entities-after-CVE-2014-3660-fix.patch

Team Nokogiri will keep on doing their best to provide security updates in a timely manner, but if this is a concern for you and want to use the system library instead; abort this installation process and reinstall nokogiri as follows:

gem install nokogiri -- --use-system-libraries
    [--with-xml2-config=/path/to/xml2-config]
    [--with-xslt-config=/path/to/xslt-config]

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

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

Note, however, that nokogiri is not fully compatible with arbitrary versions of libxml2 provided by OS/package vendors.
