Squid on CentOS
Pre-Built Binary Packages
Squid 2.6 apparently bundles with CentOS. However there is apparently no publicly available information about where to find the packages or who is bundling them. DAG and RPMforge repositories appear to no longer contain any files. Other sources imply that CentOS is an alias for RHEL (we know otherwise). Although, yes, the RHEL packages should work on CentOS.
