Loading Expect

I need to get expect/tcl loaded on a Linux machine I have access to.
Im not an admin so Im not sure what to ask for.
Here is what we are running ... a Redhat clone from what I understand.

CentOS release 6.4 (Final)
LSB_VERSION=base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch

Any help would be greatly appreciated.

Thanks

You need to ask your admin to install it.
