what is the alternative suggestion for paludis ? wrt clang, i thought we were using gcc's libstdc++ and not the libc++ project. if people are using libc++ & clang, then this news entry does not change ... you'd still need to rebuild anything using libstdc++. that said, i'm not sure libc++ & clang builds are common enough to warrant mentioning here. -mike
