I got working doing bellow steps.
1.- Download the source code vpnclient-linux-4.8.00.0490-k9.tar.gz
2.- Decompress the source code.
3.- Download patch wget -q http://tuxx-home.at/projects/cisco-vpnclient/vpnclient-linux-2.6.22.diff
4.- Apply the patch
[root@mariotpc vpnclient]# patch -i vpnclient-linux-2.6.22.diff
patching file frag.c
patching file interceptor.c
patching file IPSecDrvOS_linux.c
patching file linuxcniapi.c
patching file linux_os.h
But this is not all, remember you are patching 2.6.22!!!!
At this point compile still does not work....!!!
5.- download the source code for VPNClient vpnclient-linux-x86_64-4.8.02.0030-k9.tar.gz
Note that this is for x86_64 Kernel
6.- Decompress this source code too and Patch with the vpnclient-linux-2.6.31-final.diff
patch -i vpnclient-linux-2.6.31-final.diff
[root@mariotpc vpnclient]# patch -i vpnclient-linux-2.6.31-final.diff
patching file interceptor.c
This will modify the file interceptor.c
Just copy the interceptor.c file to the source code for x86 kernel and run the make command, after a few seconds you will have the modules and the executables ready to install
[root@mariotpc vpnclient]# cp interceptor.c ../vpnclient.86/
cp: overwrite `../vpnclient.86/interceptor.c'? y
[root@mariotpc vpnclient]# cd ../vpnclient.86/
[root@mariotpc vpnclient.86]# make

Update the GenDefs.h according the bellow file...

Great well done...!!!
GenDefs.h to be updated... as follows.
