You will need version 2.0 of libevent-dev, so you'll need
to use Ubuntu oneiric or Debian experimental when testing this.

You will need to install the following packages: git-core make
autoconf gcc pkg-config libevent-dev libtool libssl-dev

1. Setting up obfsproxy

   $ git clone git://git.torproject.org/obfsproxy.git
   $ cd obfsproxy
   $ /autogen.sh
   $ /configure && make

If git.torproject.org is blocked, try cloning it from
git://gitorious.org/obfsproxy/obfsproxy.git instead.

2. Setting up Tor

Open /etc/apt/sources.list and add the following two lines:

   deb http://deb.torproject.org/torproject.org <DISTRIBUTION> main
   deb http://deb.torproject.org/torproject.org
experimental-<DISTRIBUTION> main

Where <DISTRIBUTION> is whatever you're using, such as oneiric. Then
run the following set of commands:

   $ gpg --keyserver keys.gnupg.net --recv 886DDD89
   $ gpg --export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | sudo apt-key add -
   $ sudo aptitude update
   $ sudo aptitude install tor tor-geoipdb

If deb.torproject.org is blocked, try using deb-master.torproject.org,
mirror.netcologne.de or tor.mirror.youam.de instead. You don't need to
have Tor running straight away, but it will start by default when you
install it. Run /etc/init.d/tor stop and move on to the next step.

3. Configure Tor

Configure Tor to use bridges and talk to the obfsproxy server I set up:

   $ sudo mv /etc/tor/torrc /etc/tor/torrc.orig
   $ sudo vim /etc/tor/torrc

And put the following lines in the file:

   SocksPort 5000
   UseBridges 1
   Bridge obfs2 174.129.145.197:1051
   ClientTransportPlugin obfs2 socks5 127.0.0.1:1050

4. Start obfsproxy

It's important that you launch obfsproxy before you start Tor. Go into
the obfsproxy directory and run:

   $ ./obfsproxy --log-min-severity=debug
--log-file=obfsproxy-debug.log obfs2 socks 127.0.0.1:1050

5. Start Tor

Run the following commands to start Tor and check the log to see that
everything's ok:

   $ sudo /etc/init.d/tor start
   $ sudo tail -f /var/log/tor/log

6. Test it (need bridge running with obfsproy support)

    To test it, launch Firefox (no Torbutton needed, just a plain Firefox)
    and set it up to use a Socks server on 127.0.0.1:5000. Now browse the
    web. Win?
