net-p2p/hrktorrent-0.3.5 is available, it is updated to use rb_libtorrent 0.14.4 Tested on x86 and x64, works fine. Renaming the ebuild + changing "RDEPEND" to "~net-libs/rb_libtorrent-0.14.4" is enough to make it work.
Actually also 0.14.6 seems to work. So I've changed it to =0.14*. In portage, thanks and sorry for the delay.
