Revert "don't store Carton's tarball in the repository, pass the required version as a parameter to cpanm instead"

This reverts commit e57c177ae412de49d0e47e9b34aa556fae6d4526.
I'm reverting this change on the basis that this a production branch.
The install was working with the carton version hard coded in the repo
and anything that might screw up a working install is too risky for a
production branch

I'm happy to discuss the best approach for the truck with regard to the carton version.
