I'm at last in a position to do a build of gretl on an up-to-date version of OS X (namely 10.4.6). Mac users: please find a 1.6.0 pre-release at http://ricardo.ecn.wfu.edu/pub/gretl/gretl-1.6.0pre.dmg This package us supposed to be independent of fink (though it was built with the help of fink). To give it a true test, therefore, it's necessary to mask fink, if you have it installed. On my system I do this with # prior to testing gretl sudo /bin/mv /sw /hidden-sw # then after testing gretl sudo /bin/mv /hidden-sw /sw There are also .dmg packages for X-12-ARIMA and TRAMO/SEATS for ppc: http://ricardo.ecn.wfu.edu/pub/gretl/x12arima.dmg http://ricardo.ecn.wfu.edu/pub/gretl/tramo-seats.dmg -- Allin Cottrell Department of Economics Wake Forest University, NC
