For whatever reason it can't find the Flickr api. Did you do the 'sudo 
gem install -r flickr' step, and then add require "flickr" into your 
environment.rb file? It's complaining about an uninitialized constant 
because in your controller, on the line 'flickr = Flickr.new "..."', the 
interpreter doesn't know about the Flickr class, and since it begins 
with an uppercase character it thinks it should be a constant.

HTH,
