Could we please have Martin Liška's patch for configure included in dev-lang/ruby:2.0? dev-lang/ruby:2.1 does not need it, it is included in it. Reproducible: Always https://bugs.ruby-lang.org/issues/9692 https://bugs.ruby-lang.org/attachments/download/4342/ruby-configure-builtin_longjmp.patch
Reading the upstream bug it appears that upstream applied a different patch to 2.1 and added additional changes needed to properly fix this, and they indicate that they are not sure how to backport this to 2.0.0. I don't want to second guess them, so I don't feel comfortable to add this patch as-is. I'd rather wait for the upstream backport.
Ruby 2.0 is now masked for removal.
