transcode-0.6.0_pre5-r1 does not build. There is a undeclared symbol O_LARGEFILE in file import/nuv/rtjpeg_aud_plugin.c, line 113, function rtjpeg_aud_open. Because the old transcode-0.6.0_pre5 build successfull, i there is something wrong with the new config/use flags... This is critical, because you removed the old ebuild. By
Should be fixed in -r2.
