Your package depends explicitly on dev-lang/ruby:1.8. Versions in this slot are no longer supported upstream and this slot will be removed from Gentoo shortly. Please adapt your package to use a newer slot of ruby or mask it for removal if it is not compatible.
* @note Maintainers note * @note Please don't use this module, Matz ruby was never designed for embedding. * @note This module leaks memory, and the ruby code installs signal handlers * @note which interfere with normal operation of the server. It's all bad... * @note mruby shows some promise, feel free to rewrite the module to use that. * @note https://github.com/mruby/mruby https://github.com/FreeRADIUS/freeradius-server/blob/16fbccf6900d5cb5ad037cd22bf56f5d47a0ec2c/src/modules/rlm_ruby/rlm_ruby.c Is it okay to remove ruby from freeradius completely?
dev-lang/ruby:1.8 will be masked within a week. Since ruby support looks optional for you package please either fix the bindings or remove the ruby support before that time.
