install Eiffel Studio 5.7 (Intel build) on Max OS X 10.4.7

Greetings:

Is there anybody downloaded the ISE_EIFFEL IDE EiffelStudio5.7 for
intel mac?

http://n.ethz.ch/student/dfurrer/files/vision4mac/EiffelStudio57.app.zip

I have followed the steps and set up the environment path variables and
copied the EiffelStudio.app to /Developers/application/EiffelStudio57/

However when I launch the application from OS X it wouldn't run.

Anybody who solved the problem might give me a hand?

thanks a lot!
