As I go through the Neo4J chapter of Pragmatic Programmer's 7 Databases in 7 Weeks, I'm taking some notes to ensure that the book club members can all get set up and running effectively.
# Double check that your Java version is 7:
java -version
mvn -version
# Double check that homebrew is installed, up to date, and has no issues:
which brew
brew update
brew doctor
7d7w uses an older version of neo4j, which has the Gremlin console. Therefore, we'll need to install an older version using homebrew.
# See which versions of neo4j are in the homebrew history. We'll look for 1.9.4, which
# is the last version to support the Gremlin console.
cd $( brew --prefix )
brew versions neo4j
# Check out the 1.9.4 version of the of neo4j brew recipe and install neo4j
git checkout 8724154 Library/Formula/neo4j.rb
brew install neo4j
# Find the neo4j home directory and set NEO4J_HOME
brew info neo4j
export NEO4J_HOME=/usr/local/Cellar/neo4j/1.9.4

The Freebase data for the chapter is no longer available as a simple TSV download. I.e. this returns a 404 error:
wget http://download.freebase.com/datadumps/latest/browse/film/performance.tsv
To work around this, first download an archived Freebase backup (unfortunately, from 2010):
wget https://archive.org/download/freebase-data-dump-2010-07-16/freebase-datadump-tsv.tar.bz2
