在cent中安装fvw出现的错误，请高手帮助解决，里面有错误的信息。

操作系统版本：cent5.1
安装的软件有：管理工具，开发工具，开发库，gnome.
我在这个系统上安装fvwm2.5.25在./configure的时候出现了下面的信息

X11 libraries or header files could not be found. Please make
sure the X11 development package is installed on your system.
If it is definitely installed, try setting the include and library
paths with the --x-include and --x-libraries options of configure.
Fvwm can not be compiled without the X11 development environment.

Aborting.
然后make的时候出现了这样的信息：
make: *** 没有指明目标并且找不到 makefile。 停止。

请高手指明一条通往光明的道路，谢谢!
