Cloning

Clone recursively to pull the modified version of ALE too:

git clone git@github.com:erictzeng/ale-record.git --recursive

Installation

You may need to brew install and/or pip install a bunch of things. In particular, pygame is a pain to install. Hopefully this works for you:

pip install hg+http://bitbucket.org/pygame/pygame

We also need to compile ALE with SDL:

cd Arcade-Learning-Environment
mkdir build
cd build
cmake .. -DUSE_SDL=on
make -j8

Finally, you'll need Arcade-Learning-Environment on your PYTHONPATH. You can source .envrc in the repo root, or install the excellent direnv to have it automatically modify your path whenever you enter this directory.
