Due to changes in skbuff implemented in kernel 2.6.14, the attached patch is necessary to compile the 4.6 series of the client. Even after applying the patch, I had problems with v. 4.6.00.0045-r1, but 4.6.02.0030 seems to work fine. I haven't submitted an updated ebuild because I'm not sure how to conditionally add a patch based on kernel version...

Created attachment 83404 [details, diff] update_sk_buff.patch Patch to update calls to the 2.6.14+ kernel.
Check out cisco-vpnclient-3des-4.7.00.0640.ebuild for how to conditionally apply the patch. I'm going to go ahead and add this, I was just letting you know for the future. Also, there is already a patch in CVS for 4.6.03 and 4.7.00, I just never backported them to all of the versions.
Fixed in CVS... Thanks for the bug report and the patch!
