Hello Ifeffitters on MAC OSX.

Just to finish this thread, I inform you that I have solved my problem. The issue was with the /Library/Perl directory. Once I replaced it with a backup I diligently keep almost weekly, everything works fine with horae-056.

Thanks a lot to those who tried to help me out (and also for those who silently sympathyzed about this problem I had created to myself :-))

Stefano
