Сборка libsigc ++ завершается неудачно (явная реализация std :: basic_ostream)

Я пытаюсь установить пыл (http://ardour.org) зависимости от Mac OS 10.8 (Mountain Lion) по этой странице: http://ardour.org/building_osx_native.html.

Для этого есть два сценария, разработанные разработчиками Ardor:

• build-gtk-stack (gtk +, glib, pango, cairo …)
• build-ardor-stack (буст, рапто, libvorbis …)

Их можно найти в subversion.ardour.org/svn/ardour2/branches/2.0-ongoing/tools/.

У меня проблемы со скриптом build-ardor-stack, особенно со сборкой libsigc ++.

У меня есть этот след:

Мой GCC это:

i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00).

Как вы думаете?

Спасибо!
