No instalé la gema 'iconv', debido a errores de compilación raros.
He compilado el 'libiconv' desde el código fuente y he vinculado .h y .dylib en el directorio include y lib del rvm. cuando corroNo se pudo construir la gema iconv en ruby 1.9.2

¿Cómo puedo instalarlo y compilarlo correctamente?

Ruby 1.9 incluye el equivalente de la gema 'iconv' de forma predeterminada. No deberías necesitar la gema. Los errores, especialmente los errores "sin nombre de miembro ...", indican que la gema no es compatible con Ruby 1.9 (muchas de las estructuras para los tipos incorporados fueron, bueno, reestructuradas). –
