OS X :: Unable To Install Perl Modules For Aimsniff / Need To Install Dependencies?

I am trying to install Aim Sniff which runs through terminal. I am slowly figuring out how to use terminal to run .pl files but the readme files says I need to install these dependencies.

Code:
Requires Samba to perform SMB lookup features.

Requires the following perl modules:
Net::Pcap;
NetPacket::Ethernet qw(:strip);
NetPacket::IP qw(:strip);
NetPacket::TCP;
NetPacket::UDP;
DBI;
Unicode::String qw(utf8 latin1 utf16);
Proc::Daemon;
Proc::Simple;
FileHandle;
Unix::Syslog;
GDBM_File;
