The problem is that you are installing fedora packages into SL. They were really built for Fedora. They may actually work, but I believe that their are some packages missing from base repos for RHEL, SL, and CentOS. On RHEL, you would get those packages when you added RHEV. I don't think they exist for SL or CentOS. Look through the January messages on this board. SOmeone was doing the install on one of the EL clones and you may find more info there. Otherwise you could try using Fedora.
Thank you. Yes, I naively assumed that this would install on any reasonablly current RPM-based system, since I didn't see (and still don't see) any system requirements anywhere in any docs that suggest otherwise. All I see says "point to our yum repo and install it". When I saw the failed dependencies when I tries to install the engine, I started to suspect that this was based on a far "newer" system than I had. I have now installed Fedora 16, and will try again.
