[CentOS] Centos EL6 install issue

I am trying to install on a kvm virtual machine (host is C5).

At some point it stops with install error about cyrus-sasl.

I goto the /root/install.log in I have a number of errors about:

Installing libstdc++ warning %post scriplet failed. exit status 127 Install zlib warning %post scriptlet failed. exit status 127 Install libxml2 warning %post scriplet failed. exit status 127 this continues for a number of packages.

then the last one is :

Installing cyrus-sasl error %pre scriptlet failed. exit status 127

Any thoughts on this?

df -h shows my partition only 9% in use for where I'm installing. no errors in dmesg.

Thanks,

Jerry
