Kwajlynn on "Using MAMP for installing on Mac 10.8"

Trying to use MAMP to install wordpress on my Mac 10.8. Did all that was instructed until the last direction which is:

Lastly, we've got to run WordPress' famous 5-minute install. Visit your local site (localhost:port or localhost:port/wordpress), and enter the following information into the database setup form:

database name: wordpress
database host/server: localhost
database user: root
database password: root

Where do I find the localhost:port?

Thanks much for any help
