The sci-geosciences/mapnik-2.0.0 ebuild should depend on virtual/jpeg rather than the current media-libs/jpeg. This would align it with the mapnik-0.7.1-r2.ebuild and allow switching to libjpeg-turbo in line with recent libjpeg changes. # equery d media-libs/jpeg * These packages depend on media-libs/jpeg: sci-geosciences/mapnik-2.0.0 (media-libs/jpeg) virtual/jpeg-0 (prefix ? >=media-libs/jpeg-8d:0[static-libs?]) # emerge --oneshot media-libs/libjpeg-turbo [ebuild N ] media-libs/libjpeg-turbo-1.2.0-r1 USE="-java -static-libs" [blocks B ] media-libs/jpeg:0 ("media-libs/jpeg:0" is blocking media-libs/libjpeg-turbo-1.2.0-r1) * Error: The above package list contains packages which cannot be * installed at the same time on the same system.
