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.
