Cisco VPN client and 64bit kernel

[Eric Mittelstaedt]

Has anyone been able to successfully compile Cisco's VPN client on a 64 
bit platform?  I am using Fedora Core 3, custom kernel and I am having 
no luck with this.  I have exported -m32 within my CFLAGS, still with no 
luck.
[ericm at infineon vpnclient]$ sudo echo $CFLAGS
-m32
[ericm at infineon vpnclient]$ sudo ./vpn_install

By installing this product you agree that you have read the
license.txt file (The VPN Client license) and will comply with

Directory where binaries will be installed [/usr/local/bin]

Automatically start the VPN service at boot time [yes]y

In order to build the VPN kernel module, you must have the
kernel headers for the version of the kernel you are running.


Directory containing linux kernel source code 
[/lib/modules/2.6.9/build]/usr/src/linux-2.6.9

* Binaries will be installed in "/usr/local/bin".
* Modules will be installed in "/lib/modules/2.6.9/CiscoVPN".
* The VPN service will be started AUTOMATICALLY at boot time.
* Kernel source from "/usr/src/linux-2.6.9" will be used to build the 
module.

Is the above correct [y]y

Any help would be appreciated.
