There seems to bem some confusion about magnet links in rtorrent.

It works without patch, just type the magnetic link directly:

load.normal> magnet:?xt=urn:btih:cf87cc0d6b0db21d2221694effae3758479ad4d1&dn=Dan+Bull+-+Sharing+Is+Caring+%2B+bonus+tracks&

I’m now finishing a ruby script to download from piratebay and send to rtorrent.

To install rtorrent with MacPorts just run:

sudo port install libtorrent
sudo port install rtorrent
