Answer 1

These are not OS packages but rather modules provide for Perl, most modules can be gotten through CPAN.

Have a look here for details on how to do this. Its a fairly easy process.

Answer 2

I used these commands to install these Perl modules through CPAN:

curl -L https://raw.githubusercontent.com/miyagawa/cpanminus/master/cpanm | perl - App::cpanminus
cpanm LWP::Protocol::https
cpanm Switch
cpanm Sys::Syslog

I used cpanm but I could have used cpan command.
