The latest version of media-libs/ladspa-sdk in prefix-tree is media-libs/ladspa-sdk-1.13-r1, but there are ebuilds in gx86 that depend on >=media-libs/ladspa-sdk-1.13-r2, causing installation of those packages to break unless the offending package versions are manually masked.
bumped.
we have 1.15 for some time already
