I have to run the ./psclient.bin to get it to work. Running the ./psclient will crash as I remember it. I haven't looked at it much further than that though. It just works. So make sure you chmod on psclient.bin as well.
On another note, I have mine installed locally, didn't pick the install system wide options. (also, I'm on SuSe, not Mandrivia, but don't think that would be the problem unless you are getting specific library compatibility issues).
