Hello Ethan,

I tested NDO today on an Ubuntu "breezy" System. During ./configure i
got the following: 

configure: WARNING: linux/module.h: present but cannot be compiled
configure: WARNING: linux/module.h:     check for missing prerequisite
headers?
configure: WARNING: linux/module.h: see the Autoconf documentation
configure: WARNING: linux/module.h:     section "Present But Cannot Be
Compiled"
configure: WARNING: linux/module.h: proceeding with the preprocessor's
result
configure: WARNING: linux/module.h: in the future, the compiler will
take precedence
configure: WARNING:     ## ------------------------------------------ ##
configure: WARNING:     ## Report this to the AC_PACKAGE_NAME lists.  ##
configure: WARNING:     ## ------------------------------------------ ##


Make fails with many "redefinition of struct" and "field has incomplete
type" errors. This seems to be a problem with the ubuntu 
linux-kernel-headers package.

After some time of investigation i wondered why a userspace tool 
like nagios includes module.h. So i tried to simply remove module.h 
from the configure script:


--- configure   2005-12-23 20:00:35.000000000 +0100
+++ ../../ndoutils.12232005/configure   2005-12-26 18:12:33.000000000
+0100

 if eval "test \"\${$as_ac_Header+set}\" = set"; then



After that configure and make run fine and the tool works 
like a charm :-) IMHO it is a really great improvement!

Merry Christmas

Andreas
