You really need Math::Pari. Net::SSH::Perl will not work without it.
I already gave you instructions how to manually install Math::Pari further up in this thread because the automatic installation did not work for you. However, you did not apply these instructions or did not apply them correctly, so Math::Pari did not get installed.
Last chance, because your failure to learn makes me very tired: what happens when you manually install Math::Pari as instructed? Mind that I cannot see your screen, I do not know what you are doing and what output you see then, so you have to tell me everything. This is required! You should know this by now.
