This looks like a pretty good CLI Torrent client :P

Hi,
I think that rTorrent depends on libsigc++ which I think need at least gcc 3.x in order to build. I've tried to build it on NS 3.3 but the compiler gets confused and gets me nowhere. Maybe with some work it can be done, but I'm no C++ guru so I don't know what it would take on order for libsigc++ to build on NS 3.3
