Please stop top-posting and full-quoting. Thanks. ia32-libs is a Debianism![1] There is nothing equal on CentOS. Others have already pointed out that CentOS is multiarch and that you can install i?86 packages in parallel to the basic x86_64 arch packages. If the script you are running is hardcoded to require ia32-libs, then that install method is not compatible with CentOS. You probably will have to read the script's code to see whether it fits CentOS.

No package ia32-libs available. Error: Nothing to do

so by the quote at the top of the post,you can realize that CentOS is already packaged as compatible with 32bit & 64bit.
so now what ?
