@hstove - While running rbtc get the following error
I, [JUN 2 2014 2:37:44 PM +0530#13109] INFO -- : Fetching exchange rates

Clone the gem, in bin/rbtc, add this line, require 'active_support/all'
bundle install
gem build rbtc_arbitrage.gemspec
gem install rbtc_arbitrage-version.gem

Same problem haven't had much luck using @nurulshuvo fix either.
rvm ruby 2.1.2 / rails 4.1.6 /rbtc_arbitrage 2.4.4

Adding that require line before require 'rbtc_arbitrage' works here. Well, it gets me to the next error about httparty and the JSON lib 🌵
