I tried to build on OSX 10.6 and looks like there is a problem with c++
includes:

+ for FILE in '../src/*.cpp'
+ clang++ -c -g -Os -fPIC -nostdinc++ -I../include
../src/condition_variable.cpp
../src/condition_variable.cpp:15:1: warning: inline namespaces are a C++0x
feature [-Wc++0x-extensions]
_LIBCPP_BEGIN_NAMESPACE_STD
^
In file included from ../src/condition_variable.cpp:10:
In file included from ../include/condition_variable:110:
../include/__config:151:52: note: instantiated from:
#define _LIBCPP_BEGIN_NAMESPACE_STD namespace std {inline namespace
_LIBCPP_NAMESPACE {
                                                   ^
1 warning generated.
+ for FILE in '../src/*.cpp'
+ clang++ -c -g -Os -fPIC -nostdinc++ -I../include ../src/exception.cpp
../src/exception.cpp:14:12: fatal error: 'cxxabi.h' file not found
