************************************************************************
IMPORTANT NOTICE:
Buidling 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.
