Oh, ha, I wouldn't know, bc ckptinfo has never compiled for me, and
I'd never yet cared to beat it into compiling.

Looks like it will work for me if I do

	export KERNELHDR=/usr/include

in my shell before compiling, and use the following patch:

diff --git a/Makefile b/Makefile
index afff3f5..f7bd93b 100644
--- a/Makefile
+++ b/Makefile
