Peter, can deluge by linked against system rb_libtorrent to avoid the need to update both packages for each bug / issue in rb_libtorrent?

Comment 7 Peter Gordon 2009-06-18 16:55:27 UTC

Unfortunately, Deluge requires a lot of fairly recent API in libtorrent, which means it can only build against the system copy if it (rb_libtorrent) is 0.14+. Otherwise, it uses an internal copy which is itself an 0.14.x snapshot. :-/
