Hello,

I try to install RH9 on my Athlon600 with Videocard ATI Rage128Pro but 
anaconda fails just after start with the following lines:

Traceback (most recent call last):
File "/usr/bin/anaconda", line 465, in ?
  skipMOuseProbe = skipmouseprobe)
File "/usr/lib/python2.2/site_packages/rhpl/xserver.py", line 77, in probe HW
  videohw = videocard.VideoCardInfo(skipDDCProbe = skipDDCProbe)
File "/usr/lib/python2.2/skip_packages/rhpl/videocard.py", line 552, in 
__init__
  self.orig.videocards = copy.deepcopy(self.videocards)
  Attribute Error: 'module' object has no attribute 'deepcopy'
install exit abnormally

Anybody have a idea what the problem?
