Edit the ebuild and remove the following section: -----------------------------------cut---------------------------------- # Currently gcc-3.1.1 dont work well if we specify "-march" # and other optimizations [ -z "${CC}" ] && CC=gcc if [ "`${CC} -dumpversion`" = "3.1.1" ] || \ [ "`${CC} -dumpversion`" = "3.2" ] then export CFLAGS="${CFLAGS/pentium4/pentium3}" export CXXFLAGS="${CFLAGS/pentium4/pentium3}" fi ------------------------------------------------------------------------- NB: Just do not file a bugreport if it do not compile with your -march=pentium4 :P
