+### Packaging
+
+In order to support all distros and old libc we build and package on
+centos6.4 (64 bit). The package script takes care of cross compiling
+Influxdb for 32bit architectures.
+
+TODO: move the following to chef recipe.
+
+Below are the steps needed to setup a centos6.4 vm to build Influxdb.
+
+```
+sudo yum install git-core glibc.i686 hg bzr protobuf-compiler glibc-devel.i686 libstdc++.i686 libstdc++-devel.i686 python-pip
+sudo pip install --upgrade awscli
+git clone git@github.com:influxdb/influxdb.git
+wget http://go.googlecode.com/files/go1.1.2.linux-amd64.tar.gz
+mkdir bin
+cd bin
+tar -xzvf ../go1.1.2.linux-amd64.tar.gz
+mv go go1.1.2
+ln -s go1.1.2 go
+cd ..
+curl -L https://get.rvm.io | bash -s stable
+rvm install 1.9.3
+cd influxdb/
+git clean -dfx
+git checkout .
+git pull --rebase
