I ran the script file and it seemed to work successfully, when I ran ./psclient I was getting an error similar to the error Meracian was getting on the 1st page of this thread. I did what you told him to do, and I a similar error to Pycelle (on page 2 of the thread), except with these additional errors:

I am no Linux Expert, so this means little to me. In case it helps, I am running SuSE 8.2, My computer has an AMD Athlon 1600+, an ATI Radion 8500 LE (128MB), 512 MB DDR RAM, Soundblaster Audigy Soundcard. I do not see how my other components would have any effects.
