I tried on a clean VM and schleuder installs correctly. It looks like your system has packages from different Debian releases, and also has packages installed manually with `gem`. Is your system fully updated with regards to stable? Are there other Ruby applications installed? Any of them using `gem install`, `bundler` etc? Please provide the output of `gem list` Please provide the output of `find /usr/ -name \*.gem`
