[naemon-dev] tarball 0.8.0 fails to build rpm package on rhel6/centos6 (easy fix?)

[Anton Löfgren]

Well, sure. For development is what I'm talking about. Overriding the
default flags is pretty easy if you want to do that for whatever reason,
though and I won't even pretend to care if you do. I just assumed the
default was what we were talking about.

Or do we have something scary going on in our setup that makes this
non-trivial that I'm glossing over?
