Apologies if this is a duplicate message: thought I submitted it but can't now find it. I have a script working on windows and ubuntu, running GIMP 2.6.7. A friend tried to run same script, same version of GIMP (obtained from http://gimp.lisanet.de/Website/Download.html), his OS version 10.6.1 (also on OS version just previous). Script failed. I asked him to type (cadr '(3 2 4 5)) into script-fu console: he got Error: eval: unbound variable: cadr which suggests script-fu is seriously broken. Any thoughts?
