[Instiki] Startup errors on Debian

[Joel Konkle-Parker]

I just downloaded the latest instiki to my Debian Sarge machine with
Ruby 1.8.2. Here's what I got when I tried to start it:

# ./instiki
/root/instiki-0.10.2/vendor/rails/activesupport/lib/active_support/dependencies.rb:200:in `require': no such file to load -- markup/simple_markup (MissingSourceFile)

What am I missing?
