pkg_postinst for dev-util/ddd (3.3.12-r4 is the only version in the tree) says to enable data vizualization add the "gnuplot" useflag to ddd and then install gnuplot. The only IUSE in ddd is readline. Reproducible: Always Bug 30114 apparently introduced an RDEPEND on gnuplot, which has apparently been removed. I have no idea when the USE flag was added or dropped. I haven't used DDD in a long time, so only noticed the message when doing a full re-emerge. I don't know if the pkg_postinst message should be changed or dropped entirely. I suppose it depends on whether ddd uses it or not, and whether such use depends on it's presence at compile time or only at runtime.
Was removed in: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=5d83216d808dfbcd9bee45f61e520d84376461e4 The postinst message was edited but seems left the lines about setting the (now missing) USE. Optional but could migrate to optfeature.eclass at same time.
Hmm, thanks for the report, I'll take care of it after Christmas.
