Your package is runtime-depending on byacc standing to http://tinderbox.dev.gentoo.org/misc/rindex/dev-util/byacc . byacc is a tool used almost always at build-time, (it's either a build system or a generator - sorry this is a generic template I start with so I can't tell you right away which one). This means that it should only be depended at build-time. Please correct your ebuild or document why it is used as a runtime-dependency so that it will not be suspected again. Thanks, Diego
This was only in old versions, and it _was_ used at runtime by re2c. I just removed all the old ebuilds instead.
