Installing Ruby 2.0.0-preview1 with RVM on OS X

gistfile1.txt

# First, make sure that you have the most recent rvm. Several bugs with 2.0.0-preview1
# have recently been fixed.
#
# Second, the openssl that comes with MacOS is too old for Ruby 2.0. You need to install
# a newer one with homebrew or the rvm pkg command.

# Option 1, with homebrew openssl:

brew update
brew install openssl
rvm get head
rvm install "ruby-2.0.0-preview1" --with-openssl-dir=`brew --prefix openssl`

# Option 2, with rvm pkg install openssl:

rvm get head
rvm pkg install openssl
rvm install "ruby-2.0.0-preview1" --with-openssl-dir=$rvm_path/usr

if compiled failed with output include "Building 'ruby-2.0.0-preview1' using clang - but it's not (fully) supported, expect errors.",
you should append confirgure opts -C --with-gcc=clang , like below 

rvm install "ruby-2.0.0-preview1" --with-openssl-dir=`brew --prefix openssl` -C --with-gcc=clang

I just did this with 2.0.0 and the -C -with-gcc=clang option (from homebrew) and can confirm that it works.

Here is another ruby 2.0.0 install guide: https://coderwall.com/p/tptocq

You can just do rvm install 2.0 --with-gcc=clang.

Any idea how to install ruby 2 from source?

[UPDATE] After installing newest version of XCode and Cmd line tools it is now compiling!

I tried that and I'm having a scary error:
linking miniruby

@heliocola I'm running into the exact same error. Any hints on why this occurs?
