RHEL 5 still directly only provides Subversion 1.4.2. EPEL will not
replace it in their "Fedora backported" repositories, and you have to
reach out to RPMforge to get a reliable update or pull in the
CollabNet version, which has an entirely different structure, no
source code, and is frankly bloated for most casual use. (Commercial
support can be nice, but most of us don't need that for Subversion.)

RHEL 6, released a few days ago, is up to 1.6.11, but it's awkward to
backport due to various dependencies.
