 I can't build harfbuzz @2.5.1+universal on my OS X 10.8 system:

 {{{
 :info:build In file included from main.cc:27:
 :info:build In file included from ./hb-static.cc:27:
 :info:build In file included from ./hb.hh:176:
 :info:build In file included from /opt/local/include/gcc/c++/math.h:36:
 :info:build In file included from /opt/local/include/gcc/c++/cmath:42:
 :info:build /opt/local/include/gcc/c++/bits/cpp_type_traits.h:71:1: error:
 unknown type name '_GLIBCXX_BEGIN_NAMESPACE_VERSION'
 :info:build _GLIBCXX_BEGIN_NAMESPACE_VERSION
 :info:build ^
 }}}

 I have no idea what's going on here. Is this a problem in harfbuzz, or in
 clang, or in gcc?

 It builds fine non-universal.
