As seen on http://drobilla.net/software/lilv/, slv2 is deprecated and succeeded by lilv. I have none package installed that depends on it and long-term it should be removed from the tree. Using a grep -nr "media-libs/slv2" /usr/portage/* remaining packages depending on slv2 are: media-sound/traverso-0.49.2-r1 media-sound/ardour-2.8.12 (version 3 that uses lilv is in late beta stage) Reproducible: Always
this is more a bug that should go upstream we cant do much here: if a package needs slv2 then it'll depend on it, if it uses lv2/lilv then it'll depend on it too both libs can be installed side by side also
As for now, there are no packages depending on slv2. ardour-5.12 really links with lilv. After #685516 is resolved, this may be resolved too.
Oh, I did not notice it has some kind of resolution.
