    How to install Ruby 2.0.0-p247 on Mac OSX 10.7+

RVM:

rvm get stable && rvm reload

Firstly, the OpenSSL comes with your OSX 10.7+ is outdated, you need to get latest version
rvm pkg install openssl

Secondly, the readline library on OSX 10.7+ suffers UTF-8 issue in which method in UTF-8 is converted to characters under irb, the
fix is to use latest version
rvm pkg install readline

And you can install Ruby 2.0.0-p247 with:
rvm reinstall 2.0.0 --with-readline-dir=$rvm_path/usr --with-openssl-dir=$rvm_path/usr

Please note that clang-425.0.24 that comes with Xcode successfully compile the source, should you bump into any compilation issue, you could try compiling it with gcc-422
rbenv

Make sure your ruby-build is up-to-date:
cd ~/.rbenv/plugins/ruby-build && git pull

rbenv does not fetch fixed readline lib, thus you are required to install them manually with brew:
brew update
brew install readline openssl
CONFIGURE_OPTS="--with-readline-dir=`brew --prefix readline` --with-openssl-dir=`brew --prefix openssl`" rbenv install 2.0.0-p247

chruby + ruby-build

If you happen to use something simpler than rbenv and rvm, such as chruby, you can still use ruby-build to compile ruby into
your local ~/.rubies folder with:
brew update
brew install readline openssl
CONFIGURE_OPTS="--with-readline-dir=`brew --prefix readline` --with-openssl-dir=`brew --prefix openssl`" ruby-build 2.0.0-p247 ~/.rubies/ruby-2.0.0-p247

then insert into the top of your ~/.bash_profile to use it by default:
chruby ruby-2.0.0-p247
