Only by adding debugging statements to the module itself. This, however,
tells me you're running a too old version of Nagios. It might be possible
to replace certain headers and then get it to work, but that'll be an
exercise for you, I'm afraid. One of the tasks on my list for Nagios is
to create a nagios-devel package so that eventbroker modules can be built
against any set of headers. Right now, headers have to be shipped with
the module, and that can lead to issues like you see above.

These are known issues. I'll work around them in due time.

This is a non-issue.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
