The ebuild r7 of the blackdown java ebuild is broken for ppc. First it always downloads the i386 version because it finds it first. Even when this is changed it cannot unpack the downloaded file. Here is my fix. (worked for me) First i changed the URL otherwise it will always get the i386 file SRC_URI="ftp://metalab.unc.edu/pub/linux/devel/lang/java/blackdown.org/JDK-1.3.1/${PLATFORM}/${FCS}/${A}" Secondly, the downloaded file is not ending with bz2. Changed this also: src_unpack () { if [ $PLATFORM = "ppc" ]; then tail +422 ${DISTDIR}/${A} > j2re-1.3.1-ppc.tar tar -xjf j2re-1.3.1-ppc.tar else unpack ${A} fi } Hope this works for all regards Joerg
