I tried to install Ruby 2.0.0 with rvm install 2.0.0 this was my output:

I am running mac osx Mountan Lion. It dose the same thing if i try to install 1.9.3 What is my problem and how can i fix it? I am new to RVM and ruby so it might be just a simple mistake. Thanks in advance
When I installed Ruby 2.0 on my OS X Mountain Lion I had to ensure that OpenSSL was first installed. Since I'm using Homebrew, all I had to do a brew install openssl before rvm install 2.0.0. It looks like you're running Macports (which I haven't used before), so I guess sudo port install openssl may work for you.
Also try to install the following as well: autoconf, automake, libtool, pkg-config, libiconv, libyaml, libffi, readline, libxml2, libxslt, libksba, curl-ca-bundle, sqlite3, zlib, ncurses, gdbm - they're listed as being missing by the output you've provided.
With the next steps, I installed ruby-2.0.0-rc2 successfully.
brew update
brew install libyaml libxslt sqlite
brew upgrade automake libksba openssl pkg-config
rvm get stable
rvm autolibs enable
rvm install 2.0.0-p0
