ERROR: No recipe found at git://github.com/engineyard/eycloud-recipe-sidekiq.git (engineyard-recipes)

I receive that error when attempting to add this using engineyard-recipes:

$ ey-recipes clone git://github.com/engineyard/eycloud-recipe-sidekiq.git -n sidekiq
ERROR: No recipe found at git://github.com/engineyard/eycloud-recipe-sidekiq.git

Start by reproducing the reported `ey-recipes clone` command for `git://github.com/eycloud/eycloud-recipe-sidekiq.git` and inspect the recipe lookup path; the issue names no source files or tests. Done means determining why the repository is reported as missing and confirming that the documented clone command works or documenting the required correction.
