[gentoo-user] Where is this "GLIBCXX_3.4.9" coming from?

[felix@crowfix.com]

I can't upgrade coreutils because it complains like this:

>>> Unpacking coreutils-6.10.tar.lzma to /var/tmp/portage/sys-apps/coreutils-6.10-r1/work
lzma: /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by lzma)
tar: This does not look like a tar archive
tar: Error exit delayed from previous errors

ldd confirms something is fishy:

# ldd /usr/bin/lzma
/usr/bin/lzma: /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by /usr/bin/lzma)
        linux-gate.so.1 =>  (0xffffe000)
        libstdc++.so.6 => /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libstdc++.so.6 (0xb7e6f000)
        libm.so.6 => /lib/libm.so.6 (0xb7e49000)
        libgcc_s.so.1 => /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libgcc_s.so.1 (0xb7e3d000)
        libc.so.6 => /lib/libc.so.6 (0xb7d08000)
        /lib/ld-linux.so.2 (0xb7f97000)

But I don't have that version hanging around.

# gcc-config -l 
 [1] i686-pc-linux-gnu-4.1.2
 [2] i686-pc-linux-gnu-4.2.2 *

I tried running

    fix_libtool_files.sh 3.4.9

and it finds nothing to do.

I have remerged lxma-utils and get the same results.

I have several other packages with similar porblems, all related to
3.4.9.  Where the heck is gcc getting the 3.4.9 nonsense from?  Have I
missed some gcc upgrade step somewhere?  Should I just demerge 4.1.2
and see what else breaks?
