fedora 7 下安装网卡驱动出错，急！

公司机子上新装了fedaro 7 （所有的软件包我都选择了，我恨肯定，包特别是那些开发包和库），机子上有两块网卡。另一块是intel的，不识别，我安装驱动程式。
最后make install的时候，出现以下错误：
Makefile:73: *** Linux kernel source not found in any of these locations:
Makefile:74:
Makefile:75: *** Install the appropriate kernel development package, e.g.
Makefile:76: *** kernel-devel, for building kernel modules and try again. Stop.

请问什么原因啊？还提示要找不到内核程序阿，还提示安装其他包啊？我全部装了，一个一个校验，生怕漏了？各位兄台，给个意见啥，我什么包没装？也好网上下一个。急死了。加班都没搞定。虽搞定了我再追加分。

附makefile文件（出错相关的部分）：
