Instale o ruby-debug-ide no Snow Leopard rodando o Ruby 1.9.2

Question

Estou tentando instalar o ruby-debug-ide no Snow Leopard executando o Ruby 1.9 para que eu possa depurar o código ruby no NetBeans.

Estou usando o seguinte comando

sudo gem install ruby-debug-ide19

No entanto, continuo recebendo o seguinte erro:

nathan:mark-moseley-ruby-debug-ide-9eb626b nathan$ sudo gem install ruby-debug-ide19

Criando extensões nativas. Isso vai demorar um pouco... ERRO: Erro ao instalar o ruby-debug-ide19:  ERRO: falha ao criar extensão nativa de gem.

Alguém sabe como posso instalá-lo?

Note que eu tenho o xcode mais recente instalado, mas instalei o Ruby 1.9 usando o RVM, que eu também usei para defini-lo como o ambiente padrão do Ruby.

    

Answer 1

Resolvi sozinho instalando Ruby usando homebrew (brew install ruby). Parece que a versão RVM instala tem alguns problemas (eu experimentei a mesma coisa com várias gemas).

Eu tive que modificar manualmente os links simbólicos depois de instalar o Ruby com o homebrew, pois por padrão seu sistema ainda usaria o Ruby 1.8 que vem com o xcode.
