[gentoo-amd64] Problems customizing gentoo

[Greg]

I've been having problems customizing gentoo on my Acer Aspire T180-UA380B AMD Desktop PC.

I've been using i686 versions of gentoo for years on my pentium3 with no problems.

Here are further specs and what I've tried:

   Acer Aspire T180-UA380B AMD Desktop PC - AMD Athlon 64
   3800+ 2.4GHz, 2GB DDR2, 160GB SATA, DL DVD±RW, Gigabit LAN, Flash
   Reader, running off of a 2007.0 AMD64 live cd chrooted environment.

I keep running into the same issue no matter what USE flags I have specified in make.conf, what make.profile I have 
specified (attempted 2007.0, 2008.0, hardened, 2007.0 x86 under a 32bit chrooted environment and chost set accordingly in 
make.conf.

The error I get follows:
 * ERROR: sys-libs/glibc-2.6.1 failed.
 * Call stack:
 * ebuild.sh, line 49:  Called src_compile
 * environment, line 3362:  Called eblit-run 'src_compile'
 * environment, line 1087:  Called eblit-glibc-src_compile
 * src_compile.eblit, line 181:  Called toolchain-glibc_src_compile
 * src_compile.eblit, line 122:  Called die
 * The specific snippet of code:
 * make PARALLELMFLAGS="${MAKEOPTS}" || die "make for ${ABI} failed"
 * The die message:
 * make for default failed
 *
 * If you need support, post the topmost build error, and the call stack if relevant.
 * A complete build log is located at '/var/log/portage/sys-libs:glibc-2.6.1:20081002-111002.log'.
 * The ebuild environment file is located at '/var/build/portage/sys-libs/glibc-2.6.1/temp/environment'.
 *
  
If I start off with a stage3-amd64-2007.0 tarvol, don't try to customize my system by trying to make a stage1, and just do 
emerge --update system, I end up with errors upgrading grep regarding libpcre.

Anythoughts would be greatly appreciated as I've been struggling with this for months trying to find a solution.

If I need to provide more information or need to post this to a more appropriate list, please let me know.

Very best,
