I just installed a binary package from a local binhost to a new machine. Dependencies are missing: ldd /usr/bin/audacity |grep not\ found liblilv-0.so.0 => not found libsuil-0.so.0 => not found See https://github.com/audacity/audacity/blob/master/m4/audacity_checklib_lv2.m4
Other words, media-sound/audacity-2.1.3-r1 has automagic on media-sound/jack-audio-connection-kit:0,media-libs/lilv:0,media-libs/suil:0
this is fixed afaik
