When installing via Homebrew, dependency resolution is handled for you.
brew install saltstack
When using macports, zmq, swig, and pip may need to be installed this way:
sudo port install py-zmq
sudo port install py27-m2crypto
sudo port install py27-crypto
sudo port install py27-msgpack
sudo port install swig-python
sudo port install py-pip
For installs using the OS X system python, pip install needs to use 'sudo':
sudo pip install salt
To run salt-master on OS X, the root user maxfiles limit must be increased:
sudo launchctl limit maxfiles 4096 8192
And sudo add this configuration option to the /etc/salt/master file:
max_open_files: 8192
Now the salt-master should run without errors:
sudo /usr/local/share/python/salt-master --log-level=all
Now go to the Configuring Salt page.
