If you want to use HTTPS, then you'll need Crypt::SSLeay and IO::Socket::SSL installed. Sadly, due to USA Paranoia, we don't get these by default but they can easily be obtained from Canada (which sort of begs the question 'why make it difficult for us in the first place?')
To do this with Linux, you can just get the packages from CPAN using 'perl -MCPAN -e shell' and 'install Crypt::SSLeay'.
To do it with Windows, run 'PPM.exe' and edit/preferences to add a new Repository.
Perl 5.6: http://theoryx5.uwinnipeg.ca/ppmpackages/
Perl 5.8: http://theoryx5.uwinnipeg.ca/ppms/
Perl 5.10: http://cpan.uwinnipeg.ca/PPMPackages/10xx/
Then you can use the standard PPM interface to obtain the package.
