Problemas requiriendo gemas

Buenas,

Estoy intentando desarrollar una pequeña aplicación en Rails, pero me
surge un pequeño problema requiriendo una librería:

MissingSourceFile in TesterController#resolver

no such file to load – net/dns/resolver

El caso esque la tengo instalada (gem install net-dns):

$ irb
irb(main):001:0> require ‘rubygems’
=> true
irb(main):002:0> require ‘net/dns/resolver’
=> true

Muchas Gracias

Otro problema relacionado con las gemas :

Instalo la gema:

diego@diego:~$ gem install anemone
WARNING: Installing to ~/.gem since /usr/lib/ruby/gems/1.8 and
/usr/bin aren’t both writable.
WARNING: You don’t have /home/diego/.gem/ruby/1.8/bin in your PATH,

Pero…

instala la gemas como root
sudo gem install
y antes de eso, desinstala la gemas que no andan y volvelas a instalar

había instalado como root.
