In order to have a functional mysql-utils you would need to have the python connector. You can download it from

 http://dev.mysql.com/downloads/connector/python/  (osX 10.8 and 10.9)
 or 
 https://dev.mysql.com/downloads/connector/python/2.0.html (osX 10.7)

But I prefer to have from the .tar.gz and install it manually. You can have detailed instructions here
