We use the perl that is supplied by the OS:
$ rpm -qv perl-devel
perl-devel-5.10.1-136.el6.x86_64

However, upon checking a bit more, I noticed that RHEL *7* is using Perl
5.16.3:

$ rpm -qv perl-devel
perl-devel-5.16.3-283.el7.x86_64

So, I don't know about Amazon Linux, but they may be using something
between RHEL 6 and RHEL 7.

You can use Slony, too.

Don't they let you install external RPMs? You can grab Perl-DBIx-Safe
from CentOS repos.
