Pb installation driver ati radeon 9700 pro

Voila le pb :

-----Lorsque je fais un rpm -i ---force fglrx-glc22-4.3.0-3.2.5.i586.rpm, j'obtiens le message ci-dessous :

*** Trying to install a precompiled kernel module.
*** WARNING ***
Tailored kernel module for fglrx not present in your system.
You must go to /lib/modules/fglrx/build_mod subdir
and execute './make.sh' to build a fully customed kernel module.
Afterwards go to /lib/modules/fglrx and run './make_install.sh'
in order to install the module into your kernel's module repository.
(see readme.txt for more details.)

As of now you can still run your XServer in 2D, but hardware acclerated
OpenGL will not work and 2D graphics will lack performance.

failed.
*** Error: no kernel module build environment - please consult readme.
