I think PCSCD stands for "PC Smart Card Daemon" which provides access to the device. So the process for some reason doesn't find the group dedicated to that daemon. But it seems to me installation should forward with this error existing.
Did you do md5sum
check of the downloaded *.iso file? Did you use "Check media" option at LiveCD boot?
How do you install - via CD? Did you burn the image at the lowest speed?
