Just for the record:
I was able to compile and run psclient using Jagator51, whom I thanks deeply, linux script. I only had to recompile the CS stuff once more (First it was not recocnizing, I dont no why, the png graphic format) and then I hat to install freetype 2.9.1 to get proper fonts. I use slacware 9.1, on a pcchips lmr810 with an old duron 1.2 MHz, 256M ram, sound on board, ADSL internet connection, NVida GeForce 4 MX440SE. I have previously installed Mesa, SDL, Openal and Alsa. As anybody can see, exept for the video card, my hardware is not up to date. Even so, it workerd porperly.
Now I\'m gonna try the server.
