(merb 1.0.7.1)

The 'merb-cache' causes problem. If I delete the cache block, "rake db:automigrae" runs well.
I can not use cache on flat app?

I referenced 3 resources. 2 for init.rb and 1 for dm-do error. I followed instructions that Matt recommended. 
But I did not bundled. It only caused more complex errors with twitter API.
My git repo is git://github.com/jaigouk/twitter-on-merb.git 
(Current status: without bundling and caching, it runs well)
