Problemas na instalação de versões do Ruby via RVM no Mountain Lion

Então, eu entrei recentemente no mundo Mac e comprei um MacBook - que eu amo, aliás.

Estou tendo alguns problemas para configurar corretamente todas as minhas ferramentas de desenvolvimento e não estou 100% familiarizado com as diferenças entre a CLI Linux e a OSX CLI.

No momento, estou tentando instalar algumas versões diferentes do Ruby via RVM.

Eu tentei obter o gcc4.2 como vi recomendado, mas, independentemente do compilador que eu uso, recebo mensagens semelhantes. Nisso, estou tentando instalar o 2.0.0-preview2, mas recebo as mesmas mensagens para outras versões também:

$ rvm install 2.0.0-preview2

Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.

O OpenSSL foi instalado via homebrew:

$ brew info openssl
openssl: stable 1.0.1c
http://openssl.org

This formula is keg-only.
Mac OS X already provides this software and installing another version in
parallel can cause all kinds of trouble.

The OpenSSL provided by OS X is too old for some software.

/usr/local/Cellar/openssl/1.0.1c (429 files, 15M)
https://github.com/mxcl/homebrew/commits/master/Library/Formula/openssl.rb

Alguém poderia me apontar na direção certa? Sinto como se estivesse perdendo algo óbvio.

Desde já, obrigado.

Resolvido reinstalando o Xcode, ferramentas CLI, openssl (distribuição), autoconf (distribuição), automake (distribuição) e apple-gcc42 (distribuição). Após a reinstalação, executei rvm get head(graças a @mpapis em #rvm no freenode). rvm get headme deu o seguinte:

  * WARNING: you have 'rvm_configure_env' in /etc/rvmrc, run the following to fix:

      sudo sed -i'' -e "s#rvm_configure_env=('LDFLAGS=-L/opt/sm/pkg/active/lib CFLAGS=-I/opt/sm/pkg/active/include CPATH=/opt/sm/pkg/active/include')#rvm_configure_env=('LDFLAGS=-L/opt/sm/pkg/active/lib' 'CFLAGS=-I/opt/sm/pkg/active/include' 'CPATH=/opt/sm/pkg/active/include')#" /etc/rvmrc

RVM reloaded!

Depois disso, eu apenas corri:

sudo sed -i'' -e "s#rvm_configure_env=('LDFLAGS=-L/opt/sm/pkg/active/lib CFLAGS=-I/opt/sm/pkg/active/include CPATH=/opt/sm/pkg/active/include')#rvm_configure_env=('LDFLAGS=-L/opt/sm/pkg/active/lib' 'CFLAGS=-I/opt/sm/pkg/active/include' 'CPATH=/opt/sm/pkg/active/include')#" /etc/rvmrc

E tudo deu certo :)

Eu tive problemas semelhantes e, por fim, não tinha alguns pacotes instalados, principalmente estes:

libxslt @1.1.27_0 (active)
libyaml @0.1.4_1 (active)
llvm-3.2 @3.2_1 (active)
llvm_select @0.2_0 (active)

O llvm-3.2 é o compilador gcc que acredito ter sido o principal problema porque o openssl não foi capaz de executar ./Configure and Make.

Verifique se eles foram instalados primeiro e talvez ajude antes de ter que reinstalar tudo. Demorei 2 dias para que o Ruby 2.0.0 / Rails 3.1.1 funcionasse, espero que isso ajude alguém.
