CentOS - Jun 2009 - Error while installing packages

While installing some deps on a fresh system, I am getting the following
errors:

Anyone know why this is happening and how to deal with this?

Thanks!

>Anyone know why this is happening and how to deal with this?
Well it seems I can reproduce this in many situations if I install
using a kickstart file that has a %post command that installs open-vm-tools
from packages.vmware.com repo.

Is it not considered safe practice to execute 'yum install ' in the
%post
or is it likely package issues with that repo?

Thanks,
