Those undefined references are supplied by libstdc++, so it looks like
you have a classic case of duelling library versions.
The error messages mention gcc-3.4.6, which is actually quite old now,
so perhaps you've switched to gcc-4.x.x now?
The fix is to go back and re-emerge all packages that linked against the
old libstdc++. One way to find them is to run fix_libtool_files.sh and
note which ones get fixed. You still need to re-emerge those packages,
though, if you're now using gcc-4.x
I would actually just grep through all the .la files for "3.4.6" (assuming
that's your *old* version of gcc) and re-emerge the packages that own those
files. Maybe someone else knows an easier way.
