Installing ruby 2.0.0-dev on Mac OS X ML
Installing ruby 2.0.0-dev on Mountain Lion wasn't as straight forward as I was expecting. In order to get it working, I had to:
update rbenv and ruby-build:
brew upgrade rbenv
brew upgrade ruby-buildor, if you didn't use homebrew to install them:
cd ~/.rbenv
git pull
cd plugins/ruby-build
git pullset the CC env variable:
export CC=clangInstall openssl using homebrew, since 2.0.0-dev is incompatible with the default openssl version bundled with MacOS:
brew install opensslset configuration options that tell rbenv to use the new openssl:
export CONFIGURE_OPTS="--with-openssl-dir=`brew --prefix openssl`"And finally install ruby:
rbenv install 2.0.0-devWritten by Carlos Vilhena

where do I set the cc env and where do I change the config options for rbenv?
You can set it in the terminal (literally copy/paste the command into the terminal) or add it to your bashprofile/bashrc/zshrc/etc file and source it (e.g. source ~/.bashprofile).
But note that none of this is necessary now. rbenv install 2.0.0-p0 will download and install OpenSSL and then download and install Ruby 2, all in one smooth move.
Yeh, this was only useful when only the dev version was around. It is not needed anymore.
