Arne,
I have used Dan's RPM's on an SME b63 box, and they worked great. I have not yet tested them on the final release. Do not install any of the horde, imp, or turba rpm's. Install some or the rest of them (nag, mnemo, kronolith), and follow Dan's instructions.
I wrote a custom script to install the packages, and create some templates-custom directories. I can't remember the exact reason for this. There was something that you couldn't do when you used Dan's instructions. I'll remember just as soon as I get my test box set back up and install the packages per Dan's instructions, then install again using my script. If you can wait a couple of days, then I can provide more info. Or, you can e-mail me off-phorum and I will send you a copy of my script and you should be able to see and tell the differences.
