When booting the livecd, I get a message similar to: "Could not start 'hwsetup' - missing libpci ..." The emerge --info is the same as the one I submitted with bug #146766 I could install it and have a working system now and actually I only noticed this one when booting another system to check its available RAM.
If it only happens on one system, then it's likely a lack of memory, bad CD-ROM, or something else with the hardware.
I'm going to assume that this is FIXED with the new 2007.0 release. If not, please REOPEN the bug and we will flog the Alpha team in front of the entire town at noon.
