an administrator to make the job

Note that you don't necessarily need administrator access to install modules. Here are some options:

• Use perlbrew to install an entire build of Perl into your home directory. This requires build prerequisites such as a C compiler to be available on the machine. If this works, this is probably the best option, because you can do whatever you like with this local installation of Perl, like install all the modules you like via cpan or cpanm, etc.
• I linked you to "Yes, even you can use CPAN" above, and the replies in that thread contain more advice, such as local::lib, which makes it easier to install modules on a machine that you don't have administrator access to, by installing them in your home directory. In the local::lib docs, the section "The bootstrapping technique" describes how to install the module itself without administrator access, before using it to install other modules.
• If you're unsure about the process of installing modules itself, then "A Guide to Installing Modules" explains the basics of installing modules manually (although once they are set up, using cpan or cpanm is easier because they will automatically install dependencies as well).
• Some modules such as Net::OpenSSH are pure-Perl modules (there is no C code that needs to be compiled) with no non-core dependencies, so you can "hack" their installation by copying over their lib directory.

Note that in order to handle password authentication, Net::OpenSSH requires the XS-based module IO::Pty!.
