[aur-general] updating pkg trouble

I adopted linkage to update the version since it was outdated. i believe that it is requesting libtorrent-rasterbar but it is saying libtorrent>=0.13 is needed but there is no such version i searched for libtorrent that is atleast 0.13 and it points to rasterbar's version and i have it installed for sure but it saying i still need libtorrent>=0.13 what do i do.
