The error is related to ruby-debug19. Remove it from you gemfile and it will compile on Heroku. This has something to do with Heroku's environment.
My problem was that I had removed the ruby-debug19 from the branch that I was working on but I had forgotten to merge it with the master branch. All the time I was pushing the master branch without the changes that I had made.
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.
