After a recent emerge --depclean I noticed that media-video/movit was removed, while mlt is in fact linked against libmovit.so.3 !!! existing preserved libs: >>> package: media-video/movit-1.2.0 * - /usr/lib64/libmovit.so.3 * - /usr/lib64/libmovit.so.3.0.0 * used by /usr/lib64/mlt/libmltopengl.so (media-libs/mlt-9999) mlt used to have opengl use flag to link against libmovit.
There is no media-libs/mlt-9999 in the KDE overlay. emerge -pv mlt will show which overlay it comes from.
