How can I install s3cmd on Mac OS X Yosemite?

Or you can keep it simple and use Homebrew to install/manage many of the AWS tools, including s3cmd

1. Install Homebrew by running this command

   ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
   

2. Look for the code you want

   $ brew search s3
   s3-backer  s3cmd      s3fs   s3sync     unfs3
   

3. Install s3cmd

   brew install s3cmd
   

The installer will do all of the dirty work including get dependancies and symlink to your /Applications folder (depending on the app you install).

4. Want the latest version?

   brew update
   

I've been using this for the awscli tools for months with great success. GL.

1. Download the source of python-dateutil
2. Extract it to, e.g., /usr/local/src/python-dateutil-2.4.0
3. cd /usr/local/src/python-dateutil-2.4.0 (or whatever directory you extracted it to)
4. sudo python2.7 setup.py install
5. s3cmd --configure

(Answering my own question here. If someone can tell me why this works and the previous approach didn't I'd love to know!)

I didn't want to build it from source, and brew was complaining about needing to update xcode (*sigh)... so I created a docker image instead.

Hope this helps someone.

Usage

# setup
docker run -it --rm -v "$(pwd):/root" mountainpass/s3cmd s3cmd --configure

# run
docker run -it --rm -v "$(pwd):/root" mountainpass/s3cmd s3cmd sync ./yourfolder \
    s3://yourbucket/ \
    --acl-public \
    --add-header=Cache-Control:max-age=3600 \
    --recursive
