You receive this bug because this package does not respect my system's AR (x86_64-pc-linux-gnu-ar) and calls directly /usr/bin/ar The possible solutions to fix this issue are: 1)Fix the buildsystem, if you can; 2)inherit toolchain-funcs and use tc-export AR 3)inherit toolchain-funcs and use emake AR="$(tc-getAR)" From the build log: ar cr libisns.a server.o client.o objects.o callback.o timer.o vendor.o db.o db-file.o db-policy.o relation.o scope.o message.o security.o authblock.o policy.o pki.o register.o query.o getnext.o deregister.o esi.o scn.o dd.o entity.o portal-group.o storage-node.o domain.o simple.o tags.o attrs.o export.o socket.o slp.o error.o logging.o config.o parser.o buffer.o pidfile.o sysdep-unix.o util.o bitvector.o mdebug.o
