Can I incorporate system libraries (e.g. libxml2) I compile against into a gem (e.g. nokogiri) that I can deploy to Heroku?
问题 Nokogiri has a problem with translating to and from UTF-8 characters that turns out to come from libxml2, specifically version 2.7.6, which is the highest supported version on Ubuntu 10.04 LTS. The bug is fixed in version 2.7.7 and up, but since our app is hosted on Heroku (bamboo-ree-1.8.7 stack, based on Ubuntu 10.04), we have to use version 2.7.6, and continue to experience the bug, unless: Someone can/has hacked nokogiri to get around the problem Canonical bumps the supported libxml2
