That version of Capistrano was yanked and is no longer available from rubygems.org. You can see that on the versions page https://rubygems.org/gems/capistrano/versions.
Got here by having a similar rake-0.9.2.2 error. Figured out that I left out the appropriate require to include the bundler specific capistrano tasks in my deploy. Rb file.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
