Bug#518235: [PATCH] SOCKS, "socksify irssi" vs linking

$ socksify irssi
-!- Irssi: Unable to connect server irc.freenode.net port 6667 [No route to host]

So I brought lenny's dante up to date and did some small changes to
configure.in:

1. apt-get source irssi
2. apply patch
3. autoreconf -i
4. dpkg-buildpackage 2>&1 | tee /tmp/irssi_buil.log
5. dpkg -i irssi_0.8.12-8_i386.deb

$ irssi
-!- Welcome to the freenode Internet Relay Chat Network

Why doesn't "socksify irssi" work but linking?

[PATCH] Proxy enhancements (incl. native SOCKS5 support) 
at http://bugs.irssi.org/index.php?do=details&task_id=691
looks nice, why isn't this in trunk?
