Please attach the entire build log to this bug report.
Created attachment 360674 [details] Build log
Done. Tried to attach it when I first filed the bug, but at 3.1 MB it was over the size limit. Zipped to make it small enough to attach.
Created attachment 360684 [details] Build log I have the same problem on a different toolchain, attaching my build.log for comparison.
Can't open the first build log, feel free to upload again.
This has been brought to my attention on IRC already and it's an issue within Funtoo's gcc install. Gentoo installs C++ headers into: /usr/lib/gcc/x86_64-pc-linux-gnu/4.8.1/include/g++-v4 Funtoo installs them into: /usr/lib/gcc/x86_64-pc-linux-gnu/4.8.1/include/g++-v4.8 With clang looking for them in the former location only. Please either fix Funtoo to use the same path as Gentoo does, or ask upstream to add support for your location. In either case, you are on the wrong Bugzilla.

However GCC 4.8.1 does install in g++-v4.8 ... confusing
(In reply to Chris Kerr from comment #7) > That's not the case - my C++ headers are in g++-v4 Your 'emerge --info' then, please. If you could, I'd really appreciate the output of the failing clang invocation with '--verbose' added. If you didn't delete the build tree, that would be: /var/tmp/portage/sys-devel/llvm-3.3-r1/work/llvm-3.3.src-amd64/Release/bin/clang --verbose -fno-exceptions -fPIC -funwind-tables -I/var/tmp/portage/sys-devel/llvm-3.3-r1/work/llvm-3.3.src/projects/compiler-rt/lib -I/var/tmp/portage/sys-devel/llvm-3.3-r1/work/llvm-3.3.src/projects/compiler-rt/include -Wall -Werror -O3 -fomit-frame-pointer -m64 -fPIE -fno-builtin -fno-rtti -c -o /var/tmp/portage/sys-devel/llvm-3.3-r1/work/llvm-3.3.src-amd64/tools/clang/runtime/compiler-rt/clang_linux/msan-x86_64/x86_64/SubDir.lib__msan/msan_linux.o /var/tmp/portage/sys-devel/llvm-3.3-r1/work/llvm-3.3.src/projects/compiler-rt/lib/msan/msan_linux.cc (current directory doesn't matter)

(In reply to Chris Kerr from comment #8) > However GCC 4.8.1 does install in g++-v4.8 ... confusing Er, that's weird. My gcc 4.8.1 is in g++-v4. Are you using regular Gentoo?
It worked after upgrading to GCC 4.8.1 and following the instructions on the bugs.funtoo.org bug. Since GCC 4.8.0 is no longer in portage there is no point working out why it didn't work for me.
Ok, since the issue was fixed upstream, I will backport the patch to 3.3-r1.
+ 13 Oct 2013; Michał Górny <mgorny@gentoo.org> + +files/clang-3.3-gcc-header-path.patch, llvm-3.3-r1.ebuild: + Backport g++-X.Y header location support. Fixes bug #487584. I did that without revbump since the issue exhibited itself during build-time.
