Problemas al instalar versiones de Ruby a través de RVM en Mountain Lion

Así que recientemente me uní al mundo Mac y compré una MacBook, que por cierto me encanta.

Tengo problemas para configurar todas mis herramientas de desarrollo correctamente y no estoy 100% familiarizado con las diferencias en la CLI de Linux y la CLI de OSX.

En este momento, estoy tratando de instalar algunas versiones diferentes de Ruby a través de RVM.

He intentado obtener gcc4.2 como he visto recomendado, pero independientemente del compilador que use, recibo mensajes similares. En esto estoy tratando de instalar 2.0.0-preview2, pero también recibo los mismos mensajes para otras versiones:

$ rvm install 2.0.0-preview2

OpenSSL se ha instalado a través de 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

¿Podría alguien señalarme en la dirección correcta? Siento que me falta algo obvio.

Gracias por adelantado.

Resuelto mediante la reinstalación de Xcode, herramientas CLI, openssl (brew), autoconf (brew), automake (brew) y apple-gcc42 (brew). Después de reinstalar ejecuté rvm get head(gracias a @mpapis en #rvm en freenode). rvm get headme dio lo siguiente:

  * 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

  * No new notes to display.

RVM reloaded!

Después de eso simplemente corrí:

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

Y todo salió bien :)

Tuve problemas similares y resultó que no tenía algunos paquetes instalados, principalmente estos:

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)

llvm-3.2 es el compilador gcc que creo que fue el principal problema porque openssl no pudo ejecutar ./Configure and Make.

Compruebe si estos se instalan primero y tal vez ayude antes de tener que reinstalar todo. Me tomó 2 días para que Ruby 2.0.0 / Rails 3.1.1 funcionara, espero que esto ayude a alguien.
