Hi again,Turns out I can fix things by manually editing /usr/lib/ruby/vendor_ruby/rubygems/platform.rb, and un-doing the patch mentioned at <https://github.com/jekyll/jekyll/issues/9478#issuecomment-1785797746>. But that's obviously quite the hack; would be nice if the faulty patch could be removed from the Debian package so that one can use bundler again.
Kind regards, Ralf
