Bug 74883

After upgrading the port lang/python to version 2.4, the port
net/py-bittorrent is broken.

This appears to be an incompatibility in bittorrent's zurllib.py file; the
patch below has also been sent to the bittorrent development list.

This problem, and the same solution, appears to also apply to the port
net/bittornado.

Fix: Apply the following patch to net/py-bittorrent:
How-To-Repeat: $ btdownloadheadless.py 'http://people.freebsd.org/~scottl/5.3-torrent/5.3-RELEASE-i386-all.torrent'
