I got Net::SSH::Perl installed, and I think that's the only thing Net::SFTP directly depends on, and Net::SSH::Perl depends on everything else in the list. It took a good part of a day to install it, and it was just alot of downloading dependent modules and trying to install them, then downloading the sub-dependencies, etc. I suppose if I sort through at 'perldoc perllocal' I could tell the order they were installed in, but you might as well just start installing. Some, like Math::Pari, did not easily install, and could not install with the CPAN module (might be different now, I don't know).
