RtAudio linking error

I get the following error if I try any of the ofSoundStream examples.
(osx 10.10, current master, make)

Any idea what is going wrong here and how can it be fixed?

Compiling audioInputExample for Release
Undefined symbols for architecture x86_64:
  "RtAudio::openStream(RtAudio::StreamParameters*, RtAudio::StreamParameters*, unsigned long, unsigned int, unsigned int*, int (*)(void*, void*, unsigned int, double, unsigned int, void*), void*, RtAudio::StreamOptions*, void (*)(RtAudioError::Type, std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&))", referenced from:
      ofRtAudioSoundStream::setup(int, int, int, int, int) in libopenFrameworks.a(ofRtAudioSoundStream.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [bin/audioInputExample] Error 1
make: *** [Release] Error 2

Here is a quick and dirty workaround.
Adding this line to config.make should link rtAudio.

PROJECT_LDFLAGS += -lrtAudio -L$(OF_ROOT)/libs/rtAudio/lib/osx

I could not find any bug in the makefiles. Can anyone confirm that there is a bug?

thanks, should be fixed now
