Package dependency version requirements don't state a specific version but the minimum one supported.

Actually it is very uncommon for a Perl package to require a specific version of a dependency. It is not even supported by the toolset.

So, Net::SSH::Perl 2.14 should be ok.

In any case, take a look too at Net::SFTP::Foreign (provides much better API) and Net::SFTP::Foreign::Compat (API compatible with Net::SFTP, but uses the ssh binary under the hood, instead of Net::SSH::Perl).
