Part of the "enterprisey" nature of RHEL is that they promise no 
breaking changes within a major version. They backport security fixes, 
and leave out language feature changes. RHEL 7 is just about out (and 
the others typically lag behind it by 3-6 months on a major release), so 
we're right at the end of a release cycle. CentOS 5 had similar problems 
with a really old PHP 5.1 and Python 2.4
