Upon further analysis the current ubuntu version has a package name which does not match its soname (libtorrent11 contains /usr/lib/libtorrent.so.9.2.0). This means that it would satisfy rtorrent's libtorrent11 dependency without providing the correct soname. I will roll a patched version of rtorrent to give a safe upgrade path; I believe the debian/experimental version of libtorrent will work but should wait for the patched rtorrent.
