Index of/omeka-1.1

I have installed omeka 1.1 on a Mac version 10.5.6. I have configured the db.ini file as per instructions and named the database omeka-1.1
When I enter the address: localhost/omeka-1.1, I get the Index of /omeka-1.1 and can not complete the install process as per the install documentation.
Where am I going wrong here, and thanks for any and all help!
