I would boot with install ISO or rescueCD, chroot, make the necessary
changes and then "emerge system" and "emerge world". The necessary
changes are...
1) CFLAGS. I use...
CFLAGS="-O2 -march=native -mfpmath=sse -fomit-frame-pointer -pipe -fno-unwind-tables -fno-asynchronous-unwind-tables"
CXXFLAGS="${CFLAGS}"
2) Check your USE flags (in both make.conf and package.use). I have an
older Dell with an Intel. I have "mmx mmxext sse sse2 sse3 ssse3" USE
flags. AMD cpus benefit from "3dnow 3dnowext" and possibly other AMD-
specific flags.
