Answer 1

Похоже, у вас не установлен iconv камень.
Посмотрите похожие question.

Answer 2

Вы, вероятно, отсутствуете DevKit для окон: http://rubyinstaller.org/add-ons/devkit/

Также обратите внимание, что вы должны установить DevKit в той же арке, как вы установили рубин (то есть: и 64-разрядные версии) - госзакупки часто устанавливают один 32 и один 64 вариант и это также вызывает ошибки.

Удача
