So, as I had gone back to Ruby 1.8, I desinstalled its packages and reinstalled the 1.9 ones. I tried your first suggestion with my simple script and the script ran OK. Then I tried another more complicated script, which did not work last time ; it now runs OK too with your first hack. I haven't tried your third suggestion, as I prefer to keep my packages clean ; I keep it in mind in case the first hack does not solve my problems. Thanks a lot for your help ; I will keep you aware if my problem occurs again. Best regards JujuSL -- Posted via http://www.ruby-forum.com/.
