[Rails] undefined method `task' for #Spec::Rake::SpecTask

Any idea to fix this (I am using Rails 2.3.11): $ heroku rake db:migrate --app myapp --trace rake/rdoctask is deprecated. Use rdoc/task instead (in RDoc 2.4.2+) rake aborted! undefined method `task' for #Spec::Rake::SpecTask:0x7f690b4eecf8 /app/lib/tasks/rspec.rake:28:in `initialize'
