Perl Install problem

Hardware Arduino Yún
#1

I've been trying to run some Perl scripts that are looking for Socket.pm. I get an error saying its not in the @INC /usr/lib/perl5/5.10.
Problem is that folder isn't there at all. I did opkg install perl but i dont know if I need to do something else to get the libraries installed. I may have had this problem before but then I did a software update a few months ago and of course i lost the setup. I should have retried the script then but now its been awhile and i dont recall what I did.

#2 
opkg update 
opkg list | grep perl

opkg install perl
opkg install perlbase-base

opkg files perlbase-base

Package perlbase-base (5.10.0-7) is installed on root and has the following files:
/usr/lib/perl5/5.10/base.pm

Thank you guys! I needed a few more packages then perlbase-base but with a lot of trial and error I got it.
I assume the openwrt.org site probably has information about what files are in which packages but the site was down.
