It appears that gub has been building against aubio 3 not aubio 4. I did not realize this before. I was confused because I have to build files libaubio.py and aubio.py. The problem is that gub uses python 2.4 and and waf (this is used to build aubio4) does not support python 2.4. I am trying to see if I can upgrade python to get this to build. I had to downgrade python from 2.6 at one point because it was not building lilypond. I am looking into upgrading python back to 2.6.
