My name is Benjamin and I'm a student at Florida State University. Recently I attempted to download Gretl for one of my classes. I have a Macbook Pro version 10.6.8, and after I follow the instructions on downloading Gretl, the program itself refuses to open. When I click the Gretl Icon, it reopens the driver used to download the program, but it won't run the program itself. I've seen some tips including using X11 and the GTK framework to run the program, but typing in the README-suggested prompt in the xframe(cd /Applications/Gretl.app/Contents/Resources/bin ./gretl) produces no results. Any help you could offer in this problem would be much appreciated.
