Hi, There are several packages in the AUR which provides exactly the same package as perl-libwww from extra does. Apparently, it is a pacpan related issue and therefore these packages are required by other ones. Deleting them is likely no solution as they will get uploaded again by another pacpan user.
Cedric => perl-http-headers http://aur.archlinux.org/packages.php?ID=25730 => perl-http-request http://aur.archlinux.org/packages.php?ID=25736 => perl-http-response http://aur.archlinux.org/packages.php?ID=25735 => perl-lwp-simple http://aur.archlinux.org/packages.php?ID=27566 => perl-lwp-useragent http://aur.archlinux.org/packages.php?ID=25734
