Will do - please can you point me at where the Ruby 2.1 changes are documented?

The installation path for binary gem extensions and their documentation changed. That's why all gems with binaries failed to build on d:l:r:e for Ruby 2.1

https://build.opensuse.org/package/view_file/devel:languages:ruby/ruby/ruby.... reflects this in the %gem_base, %gem_extensions, %gem_doc_ext, and %gem_platform macros.

The latest rubygem-gem2rpm takes care of all this automatically.

On 12.3 I updated to rubygem-gem2rpm-0.9.2-58.1.x86_64 and then got: $ gem2rpm rubygem-vagrant.spec /usr/lib64/ruby/1.9.1/rubygems/package/tar_input.rb:122:in `initialize': no metadata found in rubygem-vagrant.spec (Gem::Package::FormatError) from /usr/lib64/ruby/1.9.1/rubygems/package/tar_input.rb:20:in `new' from /usr/lib64/ruby/1.9.1/rubygems/package/tar_input.rb:20:in `open' from /usr/lib64/ruby/1.9.1/rubygems/package.rb:44:in `open' from /usr/lib64/ruby/1.9.1/rubygems/format.rb:62:in `from_io' from /usr/lib64/ruby/1.9.1/rubygems/format.rb:46:in `block in from_file_by_path' from /usr/lib64/ruby/1.9.1/open-uri.rb:35:in `open' from /usr/lib64/ruby/1.9.1/open-uri.rb:35:in `open' from /usr/lib64/ruby/1.9.1/rubygems/format.rb:45:in `from_file_by_path' from /usr/lib64/ruby/gems/1.9.1/gems/gem2rpm-0.9.2/lib/gem2rpm/package.rb:11:in `rescue in initialize' from /usr/lib64/ruby/gems/1.9.1/gems/gem2rpm-0.9.2/lib/gem2rpm/package.rb:11:in `initialize' from /usr/lib64/ruby/gems/1.9.1/gems/gem2rpm-0.9.2/lib/gem2rpm.rb:35:in `new' from /usr/lib64/ruby/gems/1.9.1/gems/gem2rpm-0.9.2/lib/gem2rpm.rb:35:in `convert' from /usr/lib64/ruby/gems/1.9.1/gems/gem2rpm-0.9.2/bin/gem2rpm:132:in `<top (required)>' from /usr/bin/gem2rpm:23:in `load' from /usr/bin/gem2rpm:23:in `<main>' On 13.1 I updated rubygem-gem2rpm-0.9.2-58.1.x86_64 and then got: $ gem2rpm rubygem-vagrant.spec /usr/lib64/ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find gem2rpm (>= 0) amongst [bigdecimal-1.1.0, erubis-2.7.0, io-console-0.3, jist-1.3.1, jist-1.1.0, json-1.5.5, minitest-2.5.1, rack-1.2.5, rake-0.9.2.2, rdoc-3.9.5] (Gem::LoadError) from /usr/lib64/ruby/1.9.1/rubygems/dependency.rb:256:in `to_spec' from /usr/lib64/ruby/1.9.1/rubygems.rb:1231:in `gem' from /usr/bin/gem2rpm:22:in `<main>' $ head -n1 `which gem2rpm` #!/usr/bin/ruby1.9 $ rpm -ql rubygem-gem2rpm | head /usr/bin/gem2rpm /usr/bin/gem2rpm-0.9.2 /usr/bin/gem2rpm-opensuse /usr/lib64/ruby/gems/2.0.0/cache/gem2rpm-0.9.2.gem /usr/lib64/ruby/gems/2.0.0/gems/gem2rpm-0.9.2 /usr/lib64/ruby/gems/2.0.0/gems/gem2rpm-0.9.2/AUTHORS /usr/lib64/ruby/gems/2.0.0/gems/gem2rpm-0.9.2/LICENSE /usr/lib64/ruby/gems/2.0.0/gems/gem2rpm-0.9.2/README /usr/lib64/ruby/gems/2.0.0/gems/gem2rpm-0.9.2/bin /usr/lib64/ruby/gems/2.0.0/gems/gem2rpm-0.9.2/bin/gem2rpm $ ls -l /etc/alternatives/ruby lrwxrwxrwx 1 root root 16 Oct 20 12:42 /etc/alternatives/ruby -> /usr/bin/ruby2.0* $ ruby2.0 `which gem2rpm` rubygem-vagrant.spec package metadata is missing in rubygem-vagrant.spec Maybe I'm doing something wrong? But either way, surely these changes should be communicated on opensuse-ruby and also documented on https://en.opensuse.org/openSUSE:Packaging_Ruby ? It's a worthy goal to maintain a tool which automates everything and makes gem packagers' lives easier. But things will inevitably go wrong, and when they do, pain will be significantly reduced by clear communication and documentation. On a related note, I learned today that there has been some change in approach to handling simultaneous installation of parallel versions of gems, in a way which can involve update-alternatives. But again I have not seen any public documentation or even discussion of this change. I'm very happy to be pointed to anything I missed. Thanks!
