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!

Afaik i’ve seen similar weird issues, although locally with rake 0.9.0,
you
might want to downgrade to 0.8.7…
