Installing Openssl from source

More recently CVEs have been discovered in the latest versions of openssl available from the repos, which presents a problem for administrators since they cannot easily upgrade to a patched version. For such cases, sometimes manually compiling openssl from source is the only temporary solution until the repositories are updated or backported.
