Here are the instructions that I used to build HHVM on Mac OS 10.9 with Macports

install-hhvm-macports.sh

#!/bin/bash
git clone --recursive git://github.com/facebook/hhvm.git
cd hhvm
git checkout -t origin/HHVM-3.2

wget http://www.canonware.com/download/jemalloc/jemalloc-3.6.0.tar.bz2
tar xvf jemalloc-3.6.0.tar.bz2
cd jemalloc-3.6.0
