via package "CGI::Kwiki::Config"

That's because in CGI::Kwiki,   There's no Spoon.

There really isn't. Spoon came to Kwiki after it moved namespace from "CGI::Kwiki" to simply "Kwiki". So your error shouldn't be there, or at least it should say   via package "Kwiki::.."   instead of   via package "CGI::Kwiki..."

Best you grep for the string "CGI::Kwiki" in your installation. There's something definitely wrong where you find it. Maybe some module author mislabeled a package in a use or package statement somewhere there.
