A few of you have been having a lot of trouble with the "Laptop" script that's supposed to install a bunch of tools for you and I apologize for that, there are actually only 2 main tools that you need to have installed. If you haven't already done the developer setup yet, please follow these updated instructions instead:
Note: We'll be checking version numbers to make sure things were installed correctly, it's completely OK if your version number is not exactly the same as the ones I've given as examples below.
If you're not on OS X Lion, you will need to upgrade to it. I should have mentioned that as an up front prerequisite, so if you do need to upgrade please let me know and I'll refund you $30 to cover the cost of the upgrade.
Get it from the App Store
The download/install takes awhile so start it first. When it finishes downloading you will still need to run it to complete installation.
Install Homebrew http://mxcl.github.com/homebrew/
$ ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"
check the version number to see if it installed correctly by running:
$ brew -v
0.8.1
$ brew install git
check the version number to see if it installed correctly by running:
$ git -v
git version 1.7.7.4
Install RVM: http://rvm.io
$ curl -L https://get.rvm.io | bash -s stable --ruby
check the version number to see if it's working by opening a new tab and running $ rvm -v. You should see something like:
$ rvm -v
rvm 1.10.2 by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.beginrescueend.com/]
