At least for dev-ruby/nokogiri this is not the case. It checks the
version of libxml2 it was built against versus the one it finds at
runtime and starts to issue warnings if they don't match, but it will
still run. So it would be a good idea to automatically update nokogiri
after libxml2 to avoid cluttering logfiles and cron emails. But the ABI
didn't change.

dev-ruby/rmagick does something similar for imagemagick but actually
refuses to run, even if the ABI would stay the same.
