Guys I\'m about to kill myself with this one!
I had some problems with RVM installing multiple versions of Ruby, and following a thread on Stackoverflow I decided to rem
I ran into the same issue, you need to manually install all the required packages using Brew. For me I had to run the following installs:
brew install autoconf
brew install automake
brew install libtool
brew install apple-gcc42
brew install libyaml
brew install libxslt
brew install libksba
brew install openssl
You just need to keep running "rvm requirements" and reading the log and installing the packages needed until there are no more errors.
