I left the openswan project at version 2.6.37 along with the vast
majority of developers to create libreswan, as a result of a lawsuit
over the ownership of the name. I know several bugs creeped into
openswan since the core developers left. You should try to switch
to libreswan. See also:

Your best chance is to replace ipsec_kversion.h in the openswan source
tree with the copy from the libresawn tree. Those should address most
or maybe all issues related to compiling on different kernels.
