The typical way to install packages for perl is to use cpan or its variations (cpanm, cpanp, etc). If it is packaged by your distro thats easier/faster, but if it is not, you would still be able to do it via cpan.
cpan Log::Log4perlOR in a DOS command prompt enter
> cpan> install Log::Log4perlYou can look up the packages you want and their exact package names at search.cpan.org
