I can understand increasing permissions to allow +rx on installation directories, but why force 755, thus disallowing group writability? I've never understood this forcing of 755. I don't think Zack plans to release a new Automake. Jim and I released automake-1.16.2 in March this year. We could make another release, but it seems you have already dealt with it sufficiently. As far as I know, there are no huge outstanding problems in automake. I have been slowly trying to look at the backlog of bugs (since no one else was, for years) and at least apply patches that have been submitted. Tons remain. Of course other active contributors would be most welcome. --thanks, karl.
