implemented for this architecture"

OS: MacOS X

when I'm trying to build latest SVN libc++ I'm getting error:
[ 61%] Building CXX object lib/CMakeFiles/cxx.dir/__/src/random.cpp.o
/Users/dima/Development/C++/clang/libcxx/src/random.cpp:143:2: error: "Random
device not implemented for this
architecture"
#error "Random device not implemented for this architecture"
^
1 error generated.
make[2]: *** [lib/CMakeFiles/cxx.dir/__/src/random.cpp.o] Error 1
make[1]: *** [lib/CMakeFiles/cxx.dir/all] Error 2
make: *** [all] Error 2
if I add few lines at the beginning of the file random.cpp
#ifndef _LIBCPP_USING_DEV_RANDOM
#define _LIBCPP_USING_DEV_RANDOM
#endif
everything was fine
Note: llvm 3.6 doesn't have that problem, only source from trunk
