suse安装vmware tools时遇到的问题

我用的是vmware的版本是6.0.2。
安装的是openSuse11.0。
下面是我的安装过程:
1、把VMwareTools-6.0.2-59824.tar.gz解压到/tmp/tools中。
2、进入到/tmp/tools,执行命令:sudo ./vmware-install.pl

执行完第二步之后,就会有以下提示:

The following VMware kernel modules have been found on your system that were
not installed by the VMware Installer.  Please remove them then run this
installer again.

vmxnet
vmblock
vmmemctl
vmhgfs

Execution aborted.

这是什么意思?如何解决,谢谢!!!
