  curl -LO http://www.portaudio.com/archives/pa_stable_v19_20071207.tar.gz
  tar xzf pa_stable_v19_20071207.tar.gz
  cd portaudios
  ./configure && make && sudo make install
  cd ..
  curl -LO http://www.complang.org/ragel/ragel-6.3.tar.gz
  tar xzf ragel-6.3.tar.gz
  cd ragel-6.3
  ./configure && make && sudo make install

Now go back to bloopsaphone and

  make clean
  make ruby

(Make sure "/usr/local/bin" is in your $PATH.)

I also had to modify the portaudio Makefile to remove the -arch flags, and it worked then.
