[Nagiosplug-devel] Nagios::Plugin api

[Vonnahme, Nathan]

I guess I would first try removing the 'use 5.008004' line, getting it
the way we want it with perl 5.8, and  ignoring older perls for now-- we
should be compatible with any relatively recent build of perl, and it's
easy enough to retrofit if someone needs it.
