Yes, updating the linux include files in programs/pluto/linux26 caused
that. A proper fix will be to take only what we really need from those
include files and build our own (or require kernel headers/source to be
installed). I'll probably do a new release in a day or two that addresses
this issue.

A quick fix to pick up the linux26 directory from the previous version.

Hmm, we have never used svn for openswan. I'll have to look into that.
We hope to obsolete the natt patch soon.
