The box in concern is x86 and I also use dedicated amd64 box with distccd, crossdev and i686 toolchain emerged. Everything else builds and works well, EXCEPT dev-java/libreadline-java whose ebuild for some obscure reason calls just "gcc", which apparently causes remote distccd to call its native x86-64 gcc instead of i686, which then results in the following: gcc -I /opt/sun-jdk-1.6.0.22/include -I /opt/sun-jdk-1.6.0.22/include/linux -fPIC -DPOSIX -DJavaReadline \ -c org_gnu_readline_Readline.c gcc
