Please try 2.6.20rc1 (from testing/) as we fixed some header defines that
were wrong for some kernels.

So i've downloaded kernels directly from kernel.org.  the one i've had the most luck with is 2.6.19.  I am also using openswan 2.6.19.  Patch works fine.  Recompile the kernel, no problem.  go to make module in the openswan dir and i have problems.  Maybe there is a recommended kernel to use?  Below is the compile issues i had with make module.
