I had this same issue. I couldn't solve it though the plugin, but I was able to get perl installed manually. I used the slackware installer (upgradepkg) to install perl. After manually installing it shows up as installed and has an update ready, I can't get the update done with the plugin but perl is installed and is working. https://slackware.pkgs.org/14.2/slackware-x86_64/perl-5.22.2-x86_64-1.txz.html
