I got it installed, I have installed multiple versions of XCode 5 betas and needed to run:

sudo xcode-select -switch /Applications/Xcode5-DP6.app

To get the command=T to compile

How? I executed: git clone [e-mail]:square/maximum-awesome.git && cd maximum-awesome && rake

and I get:

$ git clone [e-mail]:square/maximum-awesome.git && cd maximum-awesome && rake

Cloning into 'maximum-awesome'...
