I suspect that the ebuild should be split as well. I suspect this may impact kget's ability to use an external libktorrent as well. In the meantime, the ktorrent-9999 ebuild doesn't compile. Reproducible: Always
ktorrent-9999 is fixed in overlay, libktorrent-9999 has been added, as well the first release candidates of libktorrent-1.0 and ktorrent-4.0
this was only in overlay bug, and it is fixed in overlay -> closed/fixed
