Is it OK to stabilize =dev-ruby/archive-tar-minitar-0.5.2-r3 ? If so, please CC arches and add STABLEREQ keyword. Stabilization of this package has been repoman-checked on the following arches: x86, amd64
No.
As clarification: we can't stable this version since it is there to support a masked ruby implementation. This will be true of many packages, so please don't file automated bugs for ruby.
