Forum: Rails-ES Error al instalar mongrel_service

Llevo dos días tratando de instalar mongrel_service en windows (he
probado en XP y 2003 server) desde gems, pero me es imposible. El
lenguaje será sencillo y potente, pero lo que es poner el servidor en
marcha un coñazo de cuidado. O que yo soy muy torpe. Veamos

Estoy usando lo siguiente:

rubyinstaller-1.9.1-p243-rc1.exe
devkit-3.4.5r3-20091110.7z

Instalo ruby con el rubyinstaller y luego, en su carpeta de instalación,
descomprimo el contenido de devkit. (de lo contrario ni me empieza la
compilación al no haber compilador instalado)

Hasta ahí bien.

Ahora hago:

gem install mongrel_service

y obtengo esto:
