请教：vmware6.5+ubuntu8.10安装vmtools过程。

zhxd

环境：VMware 6.5精简版+ubuntu8.10-server，现在想安装vmtools（kernel-headers-$、build-essential、 gcc均已安装完成），vmtools的iso文件已经下好了，但在执行./vmtool-install.pl进行安装的过程中，却出现了：

刚开始提示What is the location of the directory of C header files that match your running kernel?
于是在网上找教程，把linux-headers装了，但现在又提示：

The path "/usr/src/linux-headers-2.6.27-7/include" is a kernel header file directory, but it does not contain the file "linux/version.h" as expected.
This can happen if the kernel has never been built, or if you have invoked the "make mrproper" command in your kernel directory. In any case, you may want to rebuild your kernel.
What is the location of the directory of C header files that match your running kernel?[/usr/src/linux/include]
手工将/usr/src/linux-headers-2.6.27-7/include输入进去也是同样的结果。

请问这个问题该怎么解决呀，请这里的朋友们指点一二，我都弄两天了。
