[cfe-dev] problems building libcxx

[thecolourblue]

Hi,

I am running into some problems building libcxx. I have the latest llvm/clang and I am trying to build libcxx in tools/clang/runtime/libcxx using the just built version of clang (on osx 10.6). The errors I get are below- any ideas what I can do to get it working?
