Problème avec l'installation d'ImageMagick et de rmagick sur Mountain Lion

Je suis confronté à des problèmes avec l'installation de rmagick dans mountain lion. J'ai installé Xcode 4.4 et outils de développement. Toujours confronté à ce problème.

    Installing rmagick (2.13.1) with native extensions Unfortunately, a fatal error has occurred. Please report this error to the Bundler issue tracker at https://github.com/carlhuda/bundler/issues so that we can fix it. Thanks!
