Install Ruby and Homebrew on Mac OSX 10.7.3

install.sh

#!/bin/bash

# We are going to install the latest version of Ruby on OSX

bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)

# Now load RVM into your shell

cd ~/
sudo vim .bash_profile

# Now add this to your .bash_profile
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"

# Now restart your terminal and test

rvm

# Next step requires that you open up your Apple Store and install XCode

# Now install the latest version of Ruby

rvm install 1.9.3

# Let's make that default

rvm --default use 1.9.3

# Go ahead and install some Gems

gem install rails
gem install sinatra

#
# Alright, now you have Ruby up to date so let's get rid of Mac Ports 100%

sudo port -fp uninstall --follow-dependents installed

# This next step is optional but could be helpful if your running into errors. If you have personal apps installed here, be careful!

rm -rf \
    /opt/local \
    /Applications/DarwinPorts \
    /Applications/MacPorts \
    /Library/LaunchDaemons/org.macports.* \
    /Library/Receipts/DarwinPorts*.pkg \

    /Library/StartupItems/DarwinPortsStartup \
    /Library/Tcl/darwinports1.0 \
    /Library/Tcl/macports1.0 \
    ~/.macports

# Install Homebrew
/usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"

# Let's install something like WGET with Homebrew
brew install wget

#
# And that is that. Hope that helps a little bit?
