Just an update on mring's problems in case anyone is wondering about the status of her MAMP setup.

mring is running Mac OS X 10.3.9 (Panther) on a non-Intel Mac.

For her version of Mac OS X, the highest version of MAMP that will work is 1.3.1. Later versions of MAMP prevented Apache from starting up.

As a precaution during setup, Mac OS X's Personal Web Sharing was also turned off. Installation of Zen Cart 1.3.7 went smoothly after that.
