Hi Drew,

I've changed the Markdown engine options and forgot to handle existing
configurations.
I will fix this for the next release, but if you don't mind a bit of
hacking in the meantime, in pimki/app/models/chunks/engines.rb line 42
change to:

MAP = { :textile => Textile, :red_markdown => RedMarkdown,
:blue_markdown => BlueMarkdown, :rdoc => RDoc, :markdown =>
BlueMarkdown }

Cheers,
Assaph
