The configure defaults for gaim have changed obviously, while the USE-Flag "eds" currently controls the "--disable-gevolution" option, it must now explicitly set the "--enable-gevolution" option, to make the plugin build. In other words, line 140 frome gaim-1.5.0.ebuild reading use eds || myconf="${myconf} --disable-gevolution" must be changed to use eds && myconf="${myconf} --enable-gevolution" Reproducible: Always Steps to Reproduce: 1. 2. 3.
USE="eds" emerge gaim with the ebuild written the way it currently is does enable this plugin properly.
