psserver : error : No 3d driver

[LeSanglier]

Hello

I follow this tutorial  : http://icarus.uic.edu/~ssenne1/planeshiftcvs.html
I compile under linux with success.
I can run the ./eedit in planeshift directory.
I want to launch my own server by the script given in this website but when I do ./planeshiftserver.sh, I got this error message :

[util03@station20 PS]$ ./planeshiftserver.sh
psclient:  No 3d driver (iGraphics3D) plugin!

Does someone can give me a solution ?

Thanks in advance !
