Problem compiling VPN client under Fedora Core 6

I have the install archive for the Cisco VPN client (vpnclient-linux- x86_64-4.8.00.0490-k9), but when I try to install it, it barfs. I took the defaults as follows:

• Binaries will be installed in "/usr/local/bin".

• Modules will be installed in "/lib/modules/2.6.22.9-61.fc6/CiscoVPN".

• The VPN service will be started AUTOMATICALLY at boot time.

• Kernel source from "/lib/modules/2.6.22.9-61.fc6/build" will be used to build the module.

Here's the output: Making module make -C /lib/modules/2.6.22.9-61.fc6/build SUBDIRS=/home/john/vpnclient modules make[1]: Entering directory `/usr/src/kernels/2.6.22.9-61.fc6-i686'   CC [M]  /home/john/vpnclient/linuxcniapi.o /home/john/vpnclient/linuxcniapi.c:12:26: error: linux/config.h: No such file or directory /home/john/vpnclient/linuxcniapi.c: In function ?CniInjectReceive?: /home/john/vpnclient/linuxcniapi.c:297: warning: implicit declaration of function ?skb_set_timestamp? /home/john/vpnclient/linuxcniapi.c:331: error: ?struct sk_buff? has no member named ?nh? /home/john/vpnclient/linuxcniapi.c:332: error: ?struct sk_buff? has no member named ?mac? /home/john/vpnclient/linuxcniapi.c: In function ?CniInjectSend?: /home/john/vpnclient/linuxcniapi.c:454: error: ?struct sk_buff? has no member named ?mac? /home/john/vpnclient/linuxcniapi.c:455: error: ?struct sk_buff? has no member named ?nh? /home/john/vpnclient/linuxcniapi.c:458: error: ?struct sk_buff? has no member named ?h? /home/john/vpnclient/linuxcniapi.c:458: error: ?struct sk_buff? has no member named ?nh? make[2]: *** [/home/john/vpnclient/linuxcniapi.o] Error 1 make[1]: *** [_module_/home/john/vpnclient] Error 2 make[1]: Leaving directory `/usr/src/kernels/2.6.22.9-61.fc6-i686' make: *** [default] Error 2 Failed to make module "cisco_ipsec.ko".

Any ideas???

I will attempt to monitor this thread, but would not object to a direct email as well.         Thanks,         John
