[Ifeffit] Problem loading application on Mac OSX 10.4.7

Hello, I just downloaded ifeffit version - ifeffit-1-1.2.9-Mac10.4_horae62_pkg.dmg - to my Mac - Version 10.4.7 - and am having some trouble running the programs. When I double click on the application file I am prompted to "Please pick an output device;" my choices are either "X11 graphics" or "Aquaterm." When I choose either of them, the application fails and the icon disappears from the dock. Has anyone else encountered this problem? Is there a different version available for Mac OSX 10.4.7? Thanks, Colin
