In this case he wants a version of openssl that is not in CentOS-4.5 ...
probably because some lame "vulnerability checker" says that he needs
"greater than version 0.9.8 of openssl" to fix a specific vulnerability.

Checkers like that do not take into account that Red Hat will fix CVE's
by the backport method in their enterprise software:

http://www.redhat.com/advice/speaks_backport.html

So ... if the problem is a vulnerability checker, then what you need is
the CVE number of the problem and look for it here:

https://rhn.redhat.com/errata/rhel4as-errata.html

(go into openssl updates and look for that CVE)

You should also (if the problem is fixed) tell the maker of your scanner
that it does not take into account the Enterprise software used in 85%
of enterprise linux deployments ... and that it probably should do so if
it expects to be taken seriously in the enterprise.

Thanks,
