You should be able to load it as
require 'puppet/util/zaml'
and use ZAML instead of YAML. That's the version of YAML we're vendoring to
fix a whole list of bugs we ran into.
There's more complication going on in:
lib/puppet/util/monkey_patches.rb
showing how we monkey patch the various yaml methods on objects to actually
talk ZAML instead.
