Perl net-SSLeay 1.35 from 2008 only version available in repositories

Working with EPIC on implementing their EMR in our hospital. Perl Net-SSLeay 1.43+ is required by a component of it. Can only find version 1.35-9 on the RHEL repos while there is a versions 1.66 available from here: http://search.cpan.org/~mikem/Net-SSLeay-1.66/ ; We can install from the site directly but that may cause support issues.

Is there any reason why RHEL only has the install from 2008 in their repositories?
