You have SELinux enabled which causes the above problem. You can
either disabled SELinux or relabel the libraries of Sage. How to do
that can be found at
http://www.ittvis.com/services/techtip.asp?ttid=3092
But that is not Centos specific. Others on this list run Sage with
SELinux enabled, so hopefully they can give you more detailed input
what to do.

Yes, the RHEL ones should run out of the box on a Centos install [i.e.
RHEL 5 is the same as Centos 5, RHEL 5 Update 1 is Centos 5.1]. The
CPU type should obviously match.
