Re: db problems in 1.0.2

Yeah, I hate to say it, but Current 1.0.x probably requires at LEAST a
7.1 machine to run on. That includes the rpm errata from Red Hat.

If someone can show a broken 7.1 but working 7.2 based Current, I'll try
and fix it / work around it.

But I'm afraid 6.2 and probably 7.0 are just right out.
