1. I have moved to 1.9 long back. Don't want to move back.

2. I am on OSX. I think I had _probably_ (?) solved this issue on my 
previous laptop (PPC) -- now I;ve migrated my user to a new machine 
(Snow Leopard). All my settings, should have moved. (I say this since I 
had commented out the perl line).

LC_ALL=en_US.UTF-8
LC_CTYPE=en_US.UTF-8
LANG=C

3. Thanks for the link, i will read it. But NO, i have already read up 
enough a few months back, and do not have the energy to do it again :-(.

Thanks for the tip on -Ku / -Kn
