Well if he wants to get it with activestate it comes installed there by default. Even on linux machines that have Perl already installed everyone I have touched comes with the LWP modules already installed.
I would recommend activestate if Perl isn't already installed on your machine.They have Perl in binary format there with an executable format easy to install.
Sorry, mate, I hope it did not seem as though I was trying to nit-pick your suggestion. The distinction between a "default" and a "core" module was my only concern.
