>Description:
        The /usr/include/event.h that exists on NetBSD 4.0 is inadequate
        to build packages (mozilla packages anyway) --with-system-libevent

>How-To-Repeat:
        I use pkg_comp with NetBSD 4.0 release sets installed, and libkver
        to similate a fairly pure NetBSD 4.0 environment.  X11_TYPE=modular

        In that environment, attempting to build (for example) devel/xulrunner
        results in ...

checking for event.h... no
configure: error: --with-system-libevent requested but event.h not found
*** Error code 1

Stop.

        The same thing happens with www/seamonley, and most probably any other
        mozilla packages that exist (thunderbird?).

        Of course, event.h is found, it just doesn't work as expected, this
        is from the config.log for xulrunner:

configure:13720: checking for event.h

>Fix:
        ??   Somehow, I assume, --with-system-libevent needs to be
        disabled for NetBSD 4.0 (and probably all NetBSD 4*)
