CentOS RPM BUILDS here: http://repo.ngtech.co.il/rpm/centos/6/x86_64/
I changed the repo a bit so it can be used with yum to get updates. Add the following to a repo file: ##squid.repo [squid] name=Squid repo for CentOS Linux 6 - $basearch baseurl=http://repo.ngtech.co.il/rpm/centos/6/$basearch failovermethod=priority enabled=1 gpgcheck=0 ## For now the files are signed with an asc file and not bundled in the RPM. Later to come a RPM for the 3.3 branch. Eliezer
