why the lucky stiff

I believe you'll need to use YAML.rb 0.49.2, which is the last version which
used pure Ruby. It's a rather stable version, although it has some issues
with circular references.

As a note to all YAML users: I'm still maintaining a branch of 0.49.2 until
after 1.8 gains prevalence. Feel free to send bugfixes, support requests.
