I would set up a virtual host, I have had ez publish running on mamp pro through doing this and adding a alias into the site. All that is then required is to browse through to your installation via http://aliassetup:port# for example http://ezpublish2:8888.
if you are running mamp free it is well worth upgrading to the pro version to get all the extra features such as linking your site through to dyndns.
