Some people want a recent libtorrent (in this case the 0.12.9 sources from openSUSE 12.1) patched with the no-upload-patch made public on

http://citylight.thinkbay.net/Disable_sharing_in_rtorrent

Here you go: libtorrent-0.12.9-no_upload.tar.gz

Just tar xvfz, ./configure, make and make install.

Careful: Disables upload for all aplications using libtorrent with all consequences (superseeding!)
