I've now built a ppc variant of current CVS gretl, at http://ricardo.ecn.wfu.edu/pub/gretl/gretl-ppc.dmg
This requires prior installation of http://r.research.att.com/gtk2-framework.dmg I'm not in a position to test it, but I guess it should work on Apple ppc with X11 and OS X >= 10.3. I'd be interested to know if does in fact work! -- Allin Cottrell Department of Economics Wake Forest University
