I am having the same issue, on OpnenSuse 10.3 (Not Using KDE 4 yet).
I ran it from the desktop and it does nothing. From the terminal I get this:
./psclient.bin: error while loading shared libraries: libCgGL.so: cannot open shared object file: No such file or directory
Any Ideas? I could always do a complete reinstall of the system, but of course I would prefer not to, if its possible.
