[Gretl-users] problem with Mac OS X

Dear gretl users, I have a student who's having problems getting gretl to run on her Mac. Specifically, "When I try to open gretl, the error message "Gretl.app requires Apple's X11" pops up. However, when I try to install X11 on my computer, the error message "You cannot install X11 on this volume. Newer Software already exists on your computer." pops up. I'm not sure what this "newer software" is or why it won't work to open gretl" Is this due to the PPC architecture problem? She's shown me her laptop and there's no intel stamp on it (it's some kind of Apple machine). I've suggested that she try installing version 1.6.5, but if this is due to something else I'd appreciate any thoughts. Thanks, and I hope all you Mac folks will forgive my ignorance.
