Hi, After further debugging, I've now got the following backtrace:
a bounce message is received <internal:/usr/lib/ruby/vendor_ruby/rubygems/core_ext/kernel_require.rb>:85:in `require': cannot load such file -- charlock_holmes (LoadError) from <internal:/usr/lib/ruby/vendor_ruby/rubygems/core_ext/kernel_require.rb>:85:in `require' from /<<PKGBUILDDIR>>/lib/schleuder/cli.rb:4:in `<top (required)>' from <internal:/usr/lib/ruby/vendor_ruby/rubygems/core_ext/kernel_require.rb>:85:in `require' from <internal:/usr/lib/ruby/vendor_ruby/rubygems/core_ext/kernel_require.rb>:85:in `require' from bin/schleuder:12:in `<main>' from bounce example However, the following works as expected # ruby -v -e "require 'charlock_holmes'; puts CharlockHolmes::VERSION" ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x86_64-linux-gnu] 0.7.7 so I'm still at loss. Cheers, Georg
