Connect to Freenode via Tor with irssi

For privacy paranoids, it’s possibile to hide our own location when connecting to IRC Freenode using Tor.

Prerequisites:

• A working tor client on your workstation
• A registered nick on Freenode

What you need:

• http://freenode.net/sasl/cap_sasl.pl (irssi plugin for SASL auth) You should add or change the server for connecting to Freenode:

servers = (
  {
    address = "p4fsi4ockecnea7l.onion";
    chatnet = "freenode";
    port = "6667";
    autoconnect = "yes";
  }
);

wget the perl irssi script in and add it to autostart.

cd ~/.irssi/scripts/
wget http://freenode.net/sasl/cap_sasl.pl
cd ~/.irssi/scripts/autorun
ln -s ../cap_sasl.pl

In irssi do:

/sasl add freenode   DH-BLOWFISH
/sasl save</code></pre>

Now launch irssi using the tor wrapper, torify:
torify irssi
 As an additional note, I added a line to the perl script to make it working on my irssi:

 $VERSION = "1.1";
 
 For macports users: 
sudo port install p5-crypt-blowfish p5-crypt-dh p5-crypt-openssl-bignum \
p5-math-gmp p5-math-pari
 Although I've installed these libraries, I continue to get the error: 
Math::BigInt: couldn't load specified math lib(s), fallback to Math::BigInt::Calc at
