I've come across this problem (not with this project - but during my Googling, I came across this issue), using Resque. So, I thought I'd post to say it's maybe not down to this project, could be something more deep-seated in Rails.
[...]
** Execute resque:preload
rake aborted!
wrong constant name Cacheable-flash

[...]The module constant should be CacheableFlash, Cacheable-flash is not mentioned anywhere within my code. If I find a potential solution elsewhere, I will post it here.
When you mount an engine that contains models, the models are not recognized and an error is thrown.
In my case, we created a rails 3.1 mountable plugin called nms-cmdb and we are getting the following error output when running the 'rake erd' command:
$ rake erd --trace * Invoke erd (first_time) * Invoke erd:generate (first_time) * Invoke erd:options (first_time) * Execute erd:options * Invoke erd:load_models (first_time) * Execute erd:load_models Loading application environment... * Invoke environment (first_time) * Execute environment Loading code in search of Active Record models... rake aborted! wrong constant name Nms-cmdb /usr/local/ruby1.9.2_railspre/lib/ruby/gems/1.9.1/gems/activesupport-3.1.0/lib/active_support/dependencies.rb:378:in'
