If you are trying to download a website with LWP::UserAgent in Perl through HTTPS, you might encounter errors like this:
Can't locate object method "new" via package "LWP::Protocol::https::Socket"
Can't connect -- 501 Protocol scheme 'https' is not supported (Crypt::SSLeay or IO::Socket::SSL not installed) at somefile.pl line something.
The solution to this problem is to install the ssl development libraries, and then install the Crypt::SSLeay Perl module. To do this in Debian or Ubuntu, open a terminal and type in the following:
sudo aptitude install libssl-dev sudo cpan -i Crypt::SSLeay
This should fix your problem.
