title: Cron not working in Whenever gem
body: <p>I'm trying to use a gem whenever on my rails application, it seems like its not working because I created a task in my model and defined a method that just prints out the time.
  whenever I try to run whenever <code>-i</code> it gives me the following error</p>
  
  <pre><code> /usr/local/lib/ruby/gems/1.8/gems/whenever-0.6.2/lib/whenever/job_list.rb:21:in `initialize': undefined method `&gt;' for :environment:Symbol (NoMethodError) 
  </code></pre>
  
  <p>I don't know if I might be doing something wrong when I setup the gem. I am testing it on development environment</p>
  
  <p>My code is as follows</p>
  
  <pre><code>schedule.rb
  
  
    every 1.minutes do
      runner "Sale.unverified_notifications" , :environment &gt; :development
    end
  </code></pre>
  
  <p>and my model is as follows</p>
  
  <pre><code>   def self.unverified_notifications
       logger.info Time.now.to_s
     end
  </code></pre>
  
  <p>Please I need to know if I may be doing something wrong.</p>
  
  <p>Thank you in advance</p>
