So hi from a amd64 newbie. Not so newbie with Gentoo though. :)
My system is an Intel quad core core2 with a 2.4 GHz clock speed coupled with
a 4GB of memory. No overclocking etc. Want this to be stable. :)
I'm just curious what people use as their stable CFLAGS in amd64 Gentoo?

With only a small effort, you get most of the benefits. So fine-tuning
to the edge will give you issues to solve

Well, you say you want stable, but then say you use ~arch, so I see
you're not too stick in the mud. =:^)
Here's mine, for a dual Opteron 290:
CFLAGS=-march=opteron-sse3 -pipe -O2 -frename-registers -fweb -fmerge-
all-constants -fgcse-sm -fgcse-las -fgcse-after-reload

What has happened? What to do next?
Most of those errors seem to be portage itself choking. I just did an
update here and had a python remerge due to new USE flag (2.5.2-r8, I'm

Well sorry to not give a more details. I'm not a newbie in Gentoo just in the
amd64 side of things. Ie no

Of course (using Gentoo now for a month or so), I don't have buildpkg
in my config. So I used the manual on the URL you provided. It says
that one should emerge portage first to get a correct system first.
But when I do that, I get an error:
Yeah - once you break it you

Nice one. And probably with stellar speedup, since bunch of code gets
replaced with one or two SSE instructions.
But how relevant is it in real life examples ?

yes
also, most ebuilds don't filter march.
I was trying to install nVidia's CUDA SDK for toying with GPU as
computing tool, but I soon found out that I can't compile anything.
I always get error's like can't find -lGL etc from compiler. So I took
a look where LIBPATHetc were set and everything seemed fine.
After that, I tried with

-m32 generates 32-bit code. /usr/lib64 is only for 64-bit binaries.
Don't use -m32.
